The brake cable clamps bespeak of a 70's era or earlier frame
That's what I thought, too. They remind me of the bike that saved my life in 1978. (there's a thread around here, somewhere.) I think those clamps are lovely. Familiar.

I planned on buying a new road bike in March. Since my son is building up the John Deere, I thought it would be fun to do one at the same time, and I had been taking cursory glances at garage sales for a few months. It's a rare thing to see any kind of '70s road bike anywhere around here, so I thought I'd snatch this one up. Should be a learning experience, anyway. I can always sell it.
