I had one of these bikes some time ago...I wound up selling it. best I recall, they made only about 64 or so...I think I had number 38 and it was red. The prototype was black...and I think was owned by a guy effectionately known as Catptain Chuck, cause he owned a tour boat in Wildwood NJ.
I think they were built by a guy in 1984 or so by a guy named David Shirrell...and I heard that he at some point moved to South America somewhere and decided to build some pull wagons that looked like a sylized western flyer...But I'm not 100% sure about the last part.
I sold mine because I figured that I'd fall when riding it and ruin the fibreglass. I used the money to buy a 63 Chevy, which promptly got stolen and chopped up.
As I recall, they had some advertising flyers and busiess cards that had a golden colored backround and the black protoptyp bike on it. I seem to remember that the flyers were cut to where part of the bike was not shown.
Also the prototype had Shirrell Classic written in script around the crank sprocket cover, while the actual production models did not. I think the protptype also has quite a bit of wood in the construction. Do you have any pics of your bike?
