Austrian / French designer Alfred de Pischoff built a bare minimum ultralight in 1921-22.
The fuselage is two horizontal tubes fixed together by three other tubes. The pilot sits on a saddle and the engine, a Clerget-Blin two-cylinder rated at 16 hp, was also the bare minimum. The landing wheels were set into the lower wings.
A Mr. Pillot (in photo) and Alfred de Pischoff flew the machine. Pillot was mortally wounded when the machine crashed into the ground on 12 August 1922.
Only one copy was built.
