The Salmson-engined Arpin A-1 modified with extensions to the rudder trailing edges and mass balances added at the tops and on the ailerons. At this interim stage the pitot assembly, previously ahead of the steerable castering nosewheel, has been removed.

The Arpin A-1 seen landing in a strong 90 degree crosswind, confirmed by the windsock on the boundary at left and the smoke candle in the foreground. It was used to test the Maclaren swivelling undercarriage design.

The fuselage pod and wing centre section assembly of the Arpin A-1 was the basic structure to which all other parts were attached. It is seen here in the workshop during construction upside down, and interpretation of the features may be improved by viewing the page inverted. The works and office of M B Arpin & Co was at Longford, West Drayton, where the sole example of the A-1 was built.

Entry to both cockpits was via a door on the port side with a single recessed step, and sliding windows were fitted on both sides. The 9 cylinders of the Salmson were exposed for cooling by the slipstream.

Three-view of the Arpin A-1 Mk 2 (Cirrus Minor). Published drawings showed spats but it is unlikely that these were ever made.
