The Prini-Berthaud Biplane had two Wright-style pusher propellers, powered by a 3-cylinder water-cooled Anzani. It was an aerodynamically primitive plane, with uncambered wings, and there is no evidence that it ever flew. It was tested at Port-Aviation, France, in July 1909.
During 1937 Frank L Pringle built a two-place monoplane, registered N18546, and powered with a 45hp Szekely engine:

In 1962 Paul Price built the Price PL-2-DM, registered N850Z c/n 2,, which appears to be a much larger version of his Price Special. The PL-2-DM is also a single place, open cockpit high-wing monoplane.

The PM-280 artuca (Tortoise) was produced in 1949 by the Instituto di Aeronautica of the Politecnico di Milano in Italy to the designs of Ermenegildo Preti.
A single-seat low-wing monoplane of all-wood construction, the Tartuca is fitted with flaps and a retractable undercarriage. Power is from a 60 hp C.N.A. D4 engine.
From the time that the design was started to the test flight was only ten weeks.

In 1974 the Prestwick Man Powered Aircraft Group, made up of some Scottish Aviation Employees, announced the Dragonfly man-powered aircraft.
Its span was about 80 ft and it was nearing first flight in August 1975. It has been reported to be an ornithopter, and the Dragonfly was allocated G-BDFU.
The Prest Baby Pursuit of 1929 was a single-place monoplane with a diamond-shaped fuselage cross-section, designed by Clarence Prest. Priced at $2,100, optional engines were the 40hp Szekely SR-3 and 60hp Lawrance.
Seven were built including prototype NX876K, NX955Y, NX2304, NX13741, and NX17308/17309.
One set a world’s lightplane speed record of 101mph on 28 May 1930, using a 40hp Szekely, piloted by Prest.
