Fend Flitzer
Fend's first commercial venture was the "Flitzer," a single-seat three-wheeler with a layout the predicted the Messerschmitt. It grew out of his designs for invalid cars for disabled war veterans. In various evolutionary forms, about 300 Flitzers were made from 1948-1950.
1958 KR200 by FMR
From all accounts, the Tiger was a rapid and nimble sports car, but it cost twice as much as a KR200 (and lost the tax advantages of the 3-wheeler) and in fact was as expensive as Austin-Healey's new Sprite, a much less radical vehicle. Only 950 TG500s saw the light of day. Production ceased in 1961.
