Got this from a local guy. He knew nothing about it. It feels light but that means nothing at this point.
What I do know...
Near vertical rear dropouts w/ adjusters
26.4 or possibly 26.6 seatpost size
English threading and 68mm BB shell
BoCaMa Competition lugs
Internal cable routing on top tube
May not be original to frame
BoCaMa fork crown
Campagnolo fork ends
Most likely Reynolds 531 tubing
