Measure to see if there is any slight slope to the top tube. I'm betting the top tube near the seat lug is bit higher off the ground than close to the head tube. I believe this frame has been modified long after it was built to take modern short reach brakes. I have a hard time believing this was made that way from its beginnings. Old Paramounts (that this looks exactly like) would have used extra long Dia Compe center pull brakes. The rear dropout modification is another clue it was altered long after it was made. No builder I can think of would have used long slot 1010s with that fork crown which is much more modern. What I think a builder/painter like myself did was make a new fork and replace the rear brake bridge. This was common for people like myself to do these kind of modifications in the late 70's and 80's. Cyclery North in Chicago is one possibility for doing the redo as is Ron Boi (RRB Cycles a bit further north) is another. The 130 spacing would indicate another change taking place after 1992.
