Hi Clark,
I'd very much like to see some photos of your board, especially the tail area and its rails, just so I can see how similar it is to the Vincent.
Your board was made about three weeks before the earliest Vincent I've seen and recorded. Most the prototypes of the various models were made for the team riders, the test pilots for the new designs that Bing, Dan Bendiksen and Mike Eaton were creating in the late 60s and early 70s. Maybe that's what yours is. I can tell you for sure once I see some pictures. Please also tell me its dimensions and I'll tell you how they compare with the Vincents I've measured.
