I used to be Chester Duncan's neighbor and helped rivet the torque box for his twinny. Lost track of him over the years. Good guy.

Jim, Chester Duncan was the owner. He built the "convertible" twinny (twin, turbo charged 1275 engines) out of a shell from a car I rolled in an autocross. He started it in Seattle and finished it after he moved to Nor Cal. The car has not been around for years...decades, really. There are lots of stories I could tell about the builder and the car. Maybe when I write my memoirs!

I saw one of these back in the mid sixties at Green Valley Raceway north of Ft. Worth Texas. it was on the grid with Carrol Shelby's new Cobra and a Grand Sport Corvette driven by Delmo Johnson. To everyone's surprise the Mini was the first car into turn one. It didn't take long for American muscle to over take it.

There used to be one of these little animals in the bay area in the early seventies. It used to autocross at the ford and chevy plants. I believe a young black man owned it. Is it still around?
