Hey RJ,
I had a Velo Sport "Supra" frame/fork that I sold last year. I didn't know what model it was but I believe it was T-Mar that filled me in.
It is a very nice build with lots of frame details that make it stand out from the crowd. The Supra may have been contract built in Italy (Billato maybe?) as it shared a lot of similarities with other Italian bikes of the period, Viner for example.
