Is there any indication that there might have been wire-style chainstay guard on this frame? Does the rear triangle also have braze-on removal damage?

If so, my educated guess would be a Bridgestone Antares LDT. Vertical rear drops, geometry, and water bottle configuration match up.


The 1983 Bridgestone T500 is also a close match, but the fork crown in the closeup differs from the OP's bike. For that matter, the fork crown in the main picture doesn't look quite like the closeup either.
