The only one I have at the moment is the one from the seller's craigslist ad.
According to one of my friends, that is probably not the original crank, but I really have no idea.
Yes, definitely a 1981. As for the crankset, it appears to be a Sugno Aero Tour (TAT), in which case it is not original, as that crankset had not even been introduced in 1981. It was the first triple crankset with a 74mm BCD, allowing inner chainrings down to 24T. It was revoluntionary, when it first came out.
