Could anyone on the list be able to tell whether a particular Proteus frame was made by Yamura Yamaguchi? Does anyone know the code behind the serial numbers on the Proteus frames of the late 1970's? I have a a very clean Proteus touring frame here with some nice lugs that appear to be Prugnat lugs. I've searched the archives for a little info, but have found no real leads.
I'll post some photos soon on Yahoo.
