Bristol M.1

For a description of the format and data included in Production Tables, see here.

Type 10 M.1A
Single seat monoplane scout. Designed by Frank Barnwell, it possessed a carefully streamlined circular cross-section fuselage, which featured conventional wood and fabric construction techniques to minimise manufacturing difficulty. The fuselage was a wire braced box beam with four longerons, faired throughout its length to a circular section, the whole covered in fabric. The shoulder-mounted wing was attached to the upper longerons of the airframe. It was braced with flying wires which ran between the wing and the lower fuselage, as well as landing wires from the wings to a cabane comprising a pair of semi-circular steel tube hoops that were positioned over the pilot's cockpit, shaped so as to better facilitate the pilot's ingress and egress to their position in the cockpit. The wing possessed a wide semi-elliptical rearwards sweep at the tip, which meant that the front spar was considerably shorter than the rear and there being no inter-spar bracing being the end of the forward spar. To increase the downward vision available to the pilot, a sizable inter-spar cutout was present in the starboard wing root. One 110 h.p. Clerget 9Z powerplant driving a two bladed propeller with a large domed prop spinner closely faired to the circular cowling.

Type 11 M.1B
As M.1A but featuring a .303 in Vickers machine gun on the port wing root, a cut-out panel in the starboard wing root and a revised cabane of four straight struts arranged in a pyramid. Powerplants as indicated.

Type 20 M.1C
Production version. As M.1B with the Vickers gun centrally mounted and cut-outs were made in both wing-roots to improve the downward view. One 110 h.p. Le Rhône 9 powerplant.
