Picked up this frame for cheap at a bike salvage yard. $25, I could not resist since it is pretty cool, Italian (?, bottom bracket has Italian threads), and is my size.
There are no discernable decals for identification. There is Campagnolo decal on the chain stay and some remnants on the fork blades (unknown).
Fork steerer tube has Columbus ridges and is stamped with a "3" and backwards "S". Bottom bracket shell is stamped with "54", "53", and backwards "S". Size: seat tube 53cm c-c, 54cm c-c, BB shell 70mm, rear fork 125mm, seat post 27.2mm. Campagnolo drop-outs front and rear (has what I know to be "portacatena" holes; thank you forum members!).
