Thanks Jeff,
Denver Mullins was one of the original founders of 'Denvers Choppers' along with Mondo. Denver died in a boating accident in '92. Original Denvers frames from the 60's and 70's are nice to find. He made alot for CB750's and XS650. You could always tell a Denvers frame with the extended Gooseneck frame, long and low.
