Here's the Supaswift I found recently, with the Victa Kirby engine removed and the deck cleaned up. I like the cute Grand Prix styling. It could have been silly-looking, but it's actually quite an elegant design. The original colour of the deck was orange hammertone, which has faded to bronze where exposed to the sun. The uprights that carry the handle mechanism are silver hammertone. Notice that only three of the engine mounting holes have been used. I think that indicates that it had a Kirby engine before the Victa unit was put it. It also has two rivet holes on the side where Supaswift usually put throttles, so IF it's a 1966-67 range mower it has to be the Model 50 which came with the 143cc Kirby two-stroke. But that's a big if, it might be an unknown model from the later Sixties.
