Does anyone recognize or can identify the builder that created this seat stay wrapping up the seat lug. The bike has no other markings. Has any one see this before? Any clue as to what I might have? Is there anything else I could look for?
This seat stay treatment is often called "partial-wrap" or "semi-wrap", and the advantage is more brazed surface area, which makes for a stronger joint. Schwinn used this treatment on the higher end late eighties Greenville. MS built frames like the Circuit, Peloton, and Tempo. Lots of other builders also use this treatment in both production and custom bikes. It is not uncommon.
Curt Goodrich describes the treatment HERE in his blog.
Tim Paterek shows the partial wrap and the full wrap seat stay treatments in his framebuilding book, "The Paterek Manual".
Except for the chrome. There was an American builder that used this style back in the '70s when there really weren't very many American custom builders. But the chrome argues against that to some degree. My memories of that time are rather faded.
