I recently found this bike at a yard sale. I was immediately intrigued with the old Valentino rear derailleur, but then started looking at the lugwork and was completely stumped.

It has a single shifter braze-on for the rear and was retro-fitted for ten speed with a simplex front derailleur and Campy shifters. The link below has a few pictures and hoping the experts might be able to pinpoint who the frame builder might be:
Thanks for your help!
