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.

Circa 1936, Pilgrim built an FC-2, two-place open cockpit biplane, powered by a 220hp Wright engine and registered NR6692.

Two subsequent Pigeon aircraft were the I and much larger II, a three bladed prop biplane of which only three were made. They were used by N.A.T. in the early 1930’s.
