Built by Otto Sorrell circa 1950, the Sorrell Bathtub was a single-place, open cockpit, high wing monoplane, inspired by 1924 Dormoy Bathtub.
An “ultra-ultralight” powered by a geared-down chain-saw motor and tricycle gear, it was further developed by Michael Kimbrel, of Oakville WA, who in 1978 flew a tail-wheel version with a VW engine, then promptly sold 400 sets of drawings to home-builders.
