From Lenny: Yeah, I vaguely recall it but don't remember ever selling one.
From Dave (edited by me) :After we moved to Burton Way, and Big Twin was done, I was spending most of my time on the road, working with vendors.I hired this guy from the aerospace industry to be our designer . Unfortunately he wasn't sharp about cost or ease of manufacturing, etc.. This was his baby and it had too many pieces, too much welding, too much pressure on top plate, etc. We could not build it for the sales price.
So one was built and none ever sold....even if it didn't work right it sure would be fun to have!
