Thank you for your compliments and comments. The stem is a 1R; shift levers are Triomphe (I prefer the flaring); as far as the seat post goes, I'm not sure what model it is, but I like the clean, basic looks of it. I didn't know Supers were ever made with the GILCO "crimped" tubing. Due to the tubing I figured post 83/84, but how much later before that tubing type is no longer used. It does have the same head tube lugs that my 75/76 Super has. I don't believe it to be a Master, but I was told it could be a Mexico (?). I have a later bike than this without the GILCO tubing that might be a Nuovo Mexico (?) using different lugs, but the same fork design.
Yeah, you're right about the crimped tubing and not being a Super model. My mistake - I didn't see the crimps. Still, a beautiful bike.
