The stem and seat post are free! All it took was PB Blaster and patience. The frame has Campy dropouts, 27.2 mm seat post, Nervex lugs, so it seems to be a quality piece. The paint is really trashed, I don't think there is any hope of saving it. Derailleurs were Suntour Vx. The bike had Grab-on bar padding, so I suspect it was last worked on in the 1980s. The seat post and headset are Campy. I wonder if the bike originally came with Campy derailleurs and they were swapped with the Sun Tour at that time.
