Doug Fattic Thanks for your feedback on my mystery frame. I really appreciate your input.

If you are interested, I started another thread about it when I first got the bike. I'd still love to be able to identify the builder, so please do let me know if you think of any other leads. (Btw, I originally thought it was French, but now I don't think it its. So, ignore the original thread title. There was some unusual threading issues. It looks like the BB may have been re-threaded, and possibly the steerer, too.)
