A friend of mine just sent me this picture of a Fuso Tricycle.
I never built a Trike, maybe it's a Fuso frame that someone converted. Strangely, I always had a desire to build a Tamdem Trike; some weird masochistic urge that I never acted upon.
I would be interested to know more, just out of curiosity, if anyone has seen this or knows the owner
Mystery solved; it was built by my ex-apprentice Russ Denny. Just goes to show what a fine framebuilder he is
