It is my size. Along with two other 80's road bikes I just picked up. A new, yes new as in not ridden at all, Norco Eurosport Tri-A and a Bianchi Campion D'Italia.
It does have a riders name on it but I can't make it out. Part of it is missing. I was trying to look it up this morning. It's a strange one though. So it has me thinking it has to have been a Team bike of some sort. It even has the FD braze on. The others I have are clamped on. But the specs on it line up with the All Pro from Koga but with Miyata decals.
