My son is into Hoffman bikes.
He is basically the archivist for Matt Hoffman.
He also has 4 or 5 bikes right now. 2 of them were prototype or team rider bikes from the early 90s.
I''ll see if I can get pictures.
Post your ad on the Professional Car Forum.
They only deal in hearses, ambulances,etc.
I bet you will get some action there.
