A futher point to add, the WORKS TEAM BIKE, had a slightly sloping top tube, a wishbone rear end and was fabricated here in the UK.
That brings back memories. A windsurf shop in Shrewsbury were interested in sponsoring me and stocked Tushingham so I went in for a chat. I vaguely remember there being a stock model, and a higher end one that I think you could choose the geometry on? Either way, I was a stroppy demanding teenager and probably demanded an 8 figure salary so heard no more from them
I have been through all my boxes, the loft and the cellar to try and find the photo i know ive got of the works bike, im bloody buggered if i can find it.
For some reason i keep thinking Campagnolo, i remember being stood in the shop drooling over the brake levers.
I could be miles off of course, it could have been another brand the shop stocked. But i keep coming back to it, because the shop had only a few brands, and it would really make sense that the Uk fabricated frame came supplied with campag though, given the time we are talking about, and uk supplies at the time for small frame builders.....
