Further, for serial range B8581 - B8780 and based on the above references,
it is this authors assertion that no 504A's were in fact built and all were completed as 504J or 504K in the numbers shown. - The contract numbers for batches B3251 - B3300 and D8251 - D8300 are possibly reversed.
- Note that the Avro 504K displayed in the Canadian Aviation and Space Museum as “G-CYCK” is not in fact that
aircraft, but its provenance is worth recording. The following from the CASM website [28]:
- Built by Grahame-White
Aviation Co. Ltd. 1918, RAF registration D8971;
- No records found of history between 1918 and 1961;
- Purchased
from Mrs. G.H. Gallup, Connecticut by Maj. J.S. Appleby, Torence, California 1961;restoration started, approx. 70% completed;
- Purchased by RCAF, delivered Trenton 24 May, 1966;
- Restored 6 RD, Trenton (Crew Chief MWO H. Tate) May –
Oct 1966;
- Finished in markings of G-CYCK (RCAF), Taken on Strength (TOS) 5 Oct. 1966;
- Flown by RCAF at
Centennial Flying Displays across Canada, 1966-1967;
- Transferred to National Aeronautical Collection (now CASM)
13 March, 1968; Registered CF-CYC Ottawa, May 1969.
Note: 504K RAF registration H9717, originally assigned Canadian
registration G-CYCK, struck off strength (SOS) at Camp Borden, 8 Mar. 1922. How D8971 came to be in the US originally is unclear. - Locally referred to (confusingly) as 504L, though they were officially Avro Land Based Trainer.
- Brent [12] quotes 30 aircraft delivered in the serial range 401-432, so either 2 serials were unused or 32 aircraft were
delivered. Robertson [11] lists only 30 serials.
- Dan Hagedorn [18] "...the very first British aircraft
to arrive on Argentine shores should be a single Avro 504K - the identity of which has so far eluded historians - dropped
off in Buenos Aires by Major Frank P. Scott, representing AV. Roe & Co. Ltd, who was on his way to Chile, on 2 March 1919.....Foreign
entrepreneurs, recognizing opportunity in the pleasant Argentine environment, soon followed, and included....the Handley Page
Co. Ltd.
The Handley Page enterprise was more in the order of a commercial sales mission...... At the conclusion of
the mission on 20 December, an unspecified number of the Avro 504Ks and Bristol F.2Bs were "donated" to the Army's
Escuela Militar, de Aviacion (EMA) - the first Argentine military British-built aircraft. Finally, the Sociedad Angle-Argentina
de Aviacion, about which little is known, started training activities at Longchamps on 21 April 1921 under the guidance of
one Eduardo Miguel Hearne, using what was described as an "Avro Sport" with a 100hp Renault engine. Argentine
military use of the 504 series is, at best, confused. One 504K was, apparently, received via the "Imperial Gift"
mode (probably E3785) although nine others commonly cited as going to the Army (E9428. E9430, H1913, H2024, H2026, H6603,
H7422, H7492 and H7497) in fact were for the civil market and are almost certainly amongst the civil 504s cited earlier. Four
were definitely in EMA hands by 6 January 1921, and this had increased to 20 by 5 December 1922. a figure which held steady
as late as 17 January 1924." Further information is to be found in 'Los AVRO 504 en Argentina y el método
Gosport' by Eloy Martín [43], in Spanish, some sections of which are translated here: "Among the delegations
that visited... veteran of the RFC Frank Pilkington Scott arrived in Buenos Aires, who brought the AVRO 504K.... H2476. On July 31, 1920.....was agreed on the purchase of eight AVRO 504 Gosport (sic) biplanes (from) Handley Page Ltd. On December 22, Mr. J. Alberto Hinds, representative in Buenos Aires of the Handley Page firm, formalized the delivery
at the El Palomar aerodrome, as a donation, to the Army Aeronautical Service, of an AVRO 504K biplane. On November 6,
the National Pro-Civil and Military Aviation Commission also handed over to the Army Aeronautical Service a biplane AVRO 504K
Standard....acquired with funds from the public collection made in that Buenosairean locality. Thus between 1920 and 1922,
the Military Aviation School received twenty-two AVRO 504K Standard, painted olive green, reconditioned to new....enrolled
from 1 to 22, were in service as training and school aircraft until the end of 1927. In 1926 the Argentine army (acquired)
an AVRO 504K model (registration F8841) equipped with a.... Bristol Lucifer IV....reports of 1926 drafted by the Army Air
Service gave account of the existence of at least three units of this model." These were known as Avro Lucifer or Avro
504K Lucifer in Argentine service. According to Jackson [2], four aircraft (E444, H2512, H2562 and F8841) were exported
to Argentina via the Aircraft Disposal Company which featured standard 504K fuselage and mainplanes and 115 h.p. Bristol Lucifer
IV powereplants. Although referred to as 504N, this author believes the Argentinian term of 504K Lucifer more appropriate. airhistory.org [26] lists the serials of 13 aircraft supplied aircraft to Argentina: - H1913, H7497 Sold
Argentina (ADC Aircraft Ltd ) 04 June 1921.
- E9428, E9430, H6603, H7422, H7492 Sold Argentina (ADC Aircraft Ltd ) 04
June 1921.
- E444, F8841, H2512, H6603, H7422, H7492 To Argentina (date unspecified).
- H2562 Sold (ADC Aircraft
Ltd) unspecified.
airhistory.org also gives H2024, H2026 Sold Argentina (by ADC Aircraft Ltd.) 23 April 1921,
but also indicated as to Brazil as A2 and A3, which would appear more likely. - Loosely translated from
[45]: In 1920, Handley Page Ltd supplied one 504K with the intention of establishing of an airline in Brazil. This was short
lived and the aircraft was donated to the Brazilian government and delivered to the Navy for use in the School of Naval Aviation
(Escola de Aviação Naval). Four more Gnome Monosoupape powered aircraft were acquired in the first half of 1921,
followed by another 12 provided for in a contract concluded on May 23, 1922, configured with the 110h.p. Le Rhône.
In 1924, the four remaining aircraft were re-registered 411 to 414.
Quoted ex-RFC serials are from Andrade [19] and
airhistory.org [26]. - Alberto Fernandez Donoso and Ray Sturtivant [16] state: "(Chile)...received
two dual control Avro 504Ks under the compensation arrangements, and with Chilean numbers C-100 and C-101 ….. 12 Avro
504Ks became Chilean 71 to 82 …...Two unidentified Avro seaplanes are reported to have been supplied in 1920, fitted
with 130 h.p. Clerget engines, but possibly these were two of the series 71 to 82 fitted with floats." The same publication
shows a photograph of an Avro 504L , probably a seaplane conversion, numbered' '1'.
The article then summarises as follows: - 1919 12 Avro
504K 71-82. Some doubt as 10 numbers. Also reported as four (79-82) and six.
- 1919 2 Avro 504K C-100 and C-101 (supplied
1921?).
- 1921 10 Avro 504K Reconditioned machines with 110 hp Le Rhone, inc G-EAMO/J746 and G-EANE/J751. deld 9.21.
May only have been 5 aircraft.
Dan Hagedorn [17] replies with the following: "..in the case of the
Avro 504Ks, the serials cited by the authors (71 to 82) are a bit too straight forward, as "70" (also named Esmeralda)
is also known - apparently a second use of this number, which also appeared on an M.1C. It should probably also be pointed
out that these early serials were used in conjunction with names (at the same time - a point not made too clear in the text).
A quick look at these follows:
Serial | Name | Fate / Notes | - | General del Canto | | 70 | Esmeralda | | 75 | Avelardo Nuñez | One of the seaplanes; also named "Jabelaro Nunez"
at one point. Crashed 4 June 1922. |
76 | |
Also cited as "Esmeralda". Crashed 3 January 1921, but later cited in service
as late as 10 January 1931 as an ex-Navy machine! |
77 | Colchagua | Crashed 16 January 1922. | 78 | Capitan Avalos
| Rank may have been abreviated as painted on the aircraft. Crashed 12 July 1921. | 79 | Mallico |
Crashed
27 January 1927. | 80
| Chiloe | In service as late as September 1922. | 81 | Atacama
| Crashed 21 November 1933, by which date the name had
probably been long since dropped. |
82 | Curico | | At this point,
the Chilean Avro 504 story gets rather complicated, as serials 84,85,86, 92 and 97 are also known. It appears that C-100 and
C-101, cited by the authors, may have been ex-Navy machines, and it has been suggested that they became serials 75 and 76
respectively!"
George A. Jenks [17] follows with: - The first batch of 504Ks may well have
been for 12 aircraft in view of the rare photo illustrated in Archive 1988 No.4 which appears to show Nos. 75, 78 named Captain
Avalos and No. 82 Curico all falling within the quoted serials.
- The batch of ten aircraft reconditioned by Avro also
contained G-EAKB* according to my notes.
*Air Briain Register [55] gives G-EAKA, rather than 'KB, as sold
and marks cancelled in August 1921.
Finally, Insignia magazine [48] adds further twists: "Six Avro
504K trainers arrived in Chile during May 1919. These dual control aircraft replaced the few Blériot monoplanes then
in use at the Escuela de Aeronáutica. A National Collection was made on 27 August 1920, that raised enough funds
to purchase eight more Avro 504Ks. These machines wore a fuselage inscription with the name of the city that contributed to
its purchase. Another collection, by the public schools of Chile, enabled the acquisition of another Avro 504K". This
gives a total of 15 aircraft, but it is accompanied by a table (which covers a variety of aircraft, but makes no mention of
serials 71 through 74) that lists a total of 18 504Ks; an extract from the table is included here:
Serial | Name | Fate/Notes |
75 | J. Abelardo Nuñez | Purchaced by public school subscription. Crashed 4 June
1922. | 76
| Esmeralda | | 77 | Colchagua | Crashed 16 January 1922. |
78 | Capitan Avalos | Subsequently carried the name Malleco and then MagaIIanes. | 79 | Mallico | Crashed 27 January 1927. | 80 | Chillán | Later
Chiloé | 81 | Atacama | | 82 | Curico | | 92 | | | 97
| Jeneral Körner | | 98 | | | 99
| Jeneral del Canto | | 100 | | | 101
| | Withdrawn from service 7 June 1926. | 102 | | Withdrawn from service 7 June 1926. | 103 | | Withdrawn
from service 7 June 1926. | 104 | | Withdrawn
from service 7 June 1926. | 107 | | |
This gives some credence to Hagedorn's conjecture that "C-100 and C-101, cited
by the authors, may have been ex-Navy machines, and it has been suggested that they became serials 75 and 76 respectively",
though possibly not those precise serials. An accompanying photograph (the same as referenced by Jenks above) positively
identifies serials 75, 78, 82 and 97. - Given c/n's or original RFC serials are for batch only and
are not in direct relationship to the new military serial.
- All fitted with 100 h.p. Gnome except as
noted. When the Imperial Gift reached New Zealand they were either placed in storage or loaned to the flying schools, barnstormers
and nascent commercial operators, as indicated. When the New Zealand Permanent Air Force (NZPAF) was formed on 14 June 1923,
it was initially equipped with the surviving Avro 504Ks amongst others. From Air Britain Archive [14] : "21 Avro 504s
are listed in the .... batch of Imperial Gift aircraft rather than the normally accepted 20. The likelihood of one serial
being incorrectly quoted (possibly H1968 for H1965 for example) would explain the discrepancy, otherwise one 504 may have
found its way to New Zealand by alternative means."
- Supplied by the British Aviation Mission to
Japan in September 1921. Mikesh & Abe [6] quote 30 aircraft, supplied as 20 landplanes and 10 seaplanes. Colonel The Master
Of Semphills' report on the Mission in Flight [53] gives the aircraft supplied as Avro 504K with 110 h.p. Le Rhône and
Avro 504L with 150 h.p. Bentley BR1. Precise details of the aircraft supplied are now impossible to determine, but the Japanese
Civil Register [15] indicates 5 aircraft with c/ns falling into the Avro Hamble series: 5030, 5035, 5037, 5042 and 5044. Twenty
one Hamble c/ns, 5017 - 5039 and 5041 - 5048, are currently unaccounted, some of which could possibly apply to these aircraft.
Also in 1921, A.V. Roe & Co sold manufacturing rights to Japan, as well as 48 complete aircraft. Jackson [2] refers
to these going to the Army, but are more likely they were also supplied to the Imperial Japanese Navy. He also states that
8 of these were ex-joyriding aircraft, but Cruddas [49] does not list any of the applicable aircraft (see Temporary Ferry
Registrations list) as having flown with the Avro Transport Company. - It is not known how many, if any,
received US serials. A photo of D9028 [24] show it marked "1621", and Baugher [22] gives 1628 as ex D9038, but in
both cases the serial belonged to a Curtiss J-4A [23]. Seven surviving aircraft were shipped to the US in 1919:
- Four aircraft with British serials: D9062, D9071, D9072 and D9317. These do not appear to have received US serials.
- Two aircraft of unknown provenance received US serials: 68558, 94023.
- One unknown aircraft.
Of these, three were assigned to McCook Field, Dayton, Ohio in 1920: 94023, which received McCook Field numbers
P-141, D9062 (P-142) and one other as P-391. Baugher [22] gives serial 94062 as a 504J with McCook Field number P-142, but
Casari [23] has a Roland D.VI with this serial. - A request was made on 11 November 1918 to the British
Government for the purchase of nine Type 504s, for which Casari [21] gives seven Type 504Js (C5753, C5965, C5886, C5887, C5888,
C5889, D4365), one 504K (D8282) plus one unknown. Airhistory.org [26], based on Air Ministry Files AIR 2/136, shows 11 aircraft
delivered to the British War Mission (C5752, C5753, C5754, C5865, C5886, C5887, C5888, C5889, D4365, D8281, D8282). Probably
C5965 per Casari is in error for C5865, and the one unknown either C5752, C5754 or D8281.
Again per Casari, one machine
would appear to wrecked or otherwise disposed of, as the Order was written for just eight aircraft. These were assigned U.S.
Serial numbers 62953 - 62959, plus possibly one more. Two of these aircraft were assigned to McCook Field, Dayton, Ohio, in
September 1919: C5886 and C5887, which received McCook Field numbers P-118 and P-119 respectively, with C5886 receiving new
serial 94022 at the same time. - RFC Type 504 serial 753 landed on March 21, 1915 at St Kruis in Zeeland
and was interned into the LVA as LA-13. The 80 h.p. Gnome was replaced in 1917 by a Thulin engine. In 1918 the serial was
changed to A-21 and later to A-1 as a ground instruction airframe. Three days later, RNAS Type 504B serial 1001 landed near
Kruiningen and was interned into the LVA as LA14. Like LA13, its powerplant was replaced with a Thulin in 1917. In 1918 the
serial was changed to A-22 [51].
- Remaining aircraft were fitted with an Armstrong Siddeley Mongoose
powerplant in place the Clerget in 1931. These were then re-serialed "AM" with the original aircraft number.
- A3 serials were allocated with the formation of the RAAF in 1921.
- Per AIR 2/136.
However, Air Britain [1] has H2623 with No.29 Squadron RAF in 1925. Air Britain presumed in error.
- Per
Bruce [24], this batch of serials should all have been 504K. However, reviewing Sturtivant and Page [4] and RFC serials via
airhistory.org [26], it is clear that this was a mixed batch of 504J/504K. Analysis of [4] and [26] leads this author to reasonably
assume at least 48 504K identified, as shown in note 3.
- 12 aircraft were received in 1919 receiving
registrations M-MAAA to M-MAAL and serials 1 to 12 respectively. In 1920, a further 20 aircraft were received, being registered
M-MAAM to M-MAAZ, M-MABA, M-MABE, M-MABI, M-MABO and M-MABU with serials 13 to 31 respectively. Two other registrations are
known, M-MABD and M-MACA but their serials are unknown. At least a further 15 aircraft were received being serialed 32 to
48, with No. 40 being fitted out as an air ambulance. (From David Garbett, 24 Sept. 2018, via Air Britain Information Exchange
forum).
- 15 504Ks were received in 1921 registered M-NOAB to M-NOAP inclusive, of these M-NOAD and M-NOAE
were converted to Avro 504Ls at Barcelona. In 1922 an additional 4 504Ks were received: M-NOAT, M-NOAV, M-NOAX and M-NOAY. A further four 504Ks were
received as replacements in the second half of 1925, receiving the registrations M-NOBF, M-NOBH and two other as yet unidentified
registrations in the M-NOB* range. These last four have been quoted as being ex RAF serials E434, E445, E450 and H2057.
In June 1931, the remaining 9 aircraft were re-registered EA-FAA to EA-FAI. On 22 June 1933 the 5 surviving aircraft we
assigned numeric numbers, which were carried on the tail while the EA-F** registration remained on the fuselage, number registration
tie-up is EA-FAC = 1, EA-FAE = 2, EA-FAF = 3, EA-FAH = 4 and EA-FAI = 5. In 1935 the aircraft were again renumbered, this
time losing the EA- registration. The 4 remaining aircraft were A-1 ex 1, A-2 ex 3, A-3 ex 4 and A-4 ex 5. (From David Garbett,
24 Sept. 2018, via Air Britain Information Exchange forum). - No's 103 (2nd use of serial) and 105 were
supplied in November 1920 with 100 h. p. Sunbeam Dyak powerplants, assembled at the Kjeller aircraft factory and delivered
to the Sønnenfjeldske Flyavdelning (103) and Hærens Flyveskole (105) in July 1921. Serial 107 was presented in
June 1922 by Roald Amundsen (140hp Gnome-Rhône).
- Insignia [47] implies up to 60 504Ks were operated
by the Chinese Aviation Service between 1920 and 1923 and remaining with the Central Government until 1927. A further 2 (or
part of the previous 60?) were used by the Manchurian Air Force.
- Usually quoted as 5 aircraft supplied
to Sweden but the final 3 were supplied as 504 Mk.II.
- Both aircraft given new c/ns after crashing and being rebuilt in the Army Workshops at Kjeller and
given a new 90hp Thulin powerplant.
- The following are known to have been acquired for conversion or
export, but their fate unknown:
- D1613, D1631, F2547, F2574, F8828 and H1978, all sold by Handley Page Ltd.
- E442 and H6654 sold by ADC Aircraft Ltd.
- F2548 sold abroad (unknown vendor).
- H9771 - H9812 delivered
as salvage, of which H9645, H9772, H9774, H9777, H9778, H9786, H9793, H9794, H9795, H9799, H9802, H9807 to ADC.
In addition, of the batch J743 - J763 plus J803, all re-purchased by Avro, J744 and J750 are accounted for. These could
provide some of the exports for which no provenance is given in the table. Serials J765 - J802, J804 - J1023 went straight
to store except J833, J835, J869, J875, J1015, and provided many of the airframes for those marked as "Built from Spares" - From George Jenks [52]: "The Mexican Air Force operated a batch of at least six Avro 504Ks fitted
with what appears to be a slightly different (earlier?) version of the modified [504 Mk.II] undercarriage, These were apparently indigenously built under licence from Avros as the Anahuac but may have been erected
from parts, as sometimes happened, supplied by the company in 1921/22. According to R.T. Jackson, in the latest edition of
the Putnam Avro book, E9412 was imported into Mexico from the UK. It is not known if this was for use as a pattern aircraft,
and was therefore fitted with the undercarriage in question, or if the design was produced by Avros under either of the original
designations 504K Mk.II or 504N in 1921/22."
- Per Andersson [58], British intervention forces brought about 30 Type 504Ks to Russia
during the Civil War. Known aircraft are E3548, E3582, E3583, E3707, H2280 (or possibly F2280), H9673 - H9678 (unloaded from
SS Diyatalawa at Novorossisk, 25 Jan 1920), H9747 - H9758.
- Commissioned by the Portuguese Government through
Vickers Ltd, but under contract C.1113 / 23 of November 10, 1923 to Avro, consequently all have Avro c/ns. The c/ns are per
the Ex OGMA blog [59], except this author believes that three are in error; the blog has R3/LE/12033, 12084 and 12402 which
this author believes should be 12133, 12184 and 12422
repectively and have been corrected accordingly.
These 30 aircraft were distributed as follows: 14 aircraft ito Escola
de Aeronáutica (EMA – Military Aviation School), 13 to the Esquadrilha de Treino e Depósito (Training
and Depot Squadron) and 3 to No.1 Fighter Squadron. Later, 3 aircraft were transferred to the Aviação Naval
(Naval Aviation).
