1060 Corsa dropouts out back, that could date to mid-70s IIRC

Seat stays at cluster reminds me of the treatment Cinelli, Toressini (thus Torpado, Italvega etc., right?) and others used on their 70s bikes.

Looks like maybe powdercoat, and way too thick. Cutout in BB doesn't ring a bell. Sad to see the BB guides shaved, the under-chainstay stop ignored, and someone used a clamp on chrome, wtf? (edit: Probably because BB guides are shaved, duh!)

Nice looking though. Any info on the BB or steer tube threading?

Could be really cool to have it stripped, fresh BB guides brazed on, and a repaint.
