well to be honest its my first road frame but it seems to fit me fine! I can't look at the bike right now so I didn't know if anyone would know off the top of their head. I'll have a look at the bike shortly and get back to you.
I only ask the fit question because it seems like a lot of people buy vintage frames for conversions and get so caught up in a particular deal for a particular bike that they fancy and they forget to check sizing. I've been there—the first road bike I bought was a 1985 Nishiki sized at about 50-52 cm... I usually ride 56-58.
In any case, this forum is only going to be helpful with questions specifically about converting—and you'll be lucky if it's helpful even for that.
Any other questions you have, you're going to be much better off asking the Classic and Vintage forum. I'm sure there are people that'll be able to identify this bike within seconds, but they don't hang out in SSFG.
