Checked the locknuts and the're from '67.
The Pista crankset has a 151 BCD, so it's pre-67.
I'm not sure if the seatpost is original. It's a 2-bolt unfluted post, but it's been milled down on a lathe from 26.8 to 26.4. Not sure if the original broke, or if the original owner just didn't want to bother with buying a new post. Sketchy, I know, but I weigh like 135...
As for the sticker, it looks like the '69 version - gold foil. The earlier columbus looks like a decal, which mine definitely isn't.
So, I'm figuring late 60s. Thanks for your help.
Some more eye candy, chained revolution's new ride, a '52 Pista
