You're right, of course. The equipment is all wrong for 1967, per Chuck Schmidt's Campy Timeline. The 144 BCD triple crank was only just introduced in 1967, and I doubt Schwinn would have adopted it so quickly. The Superleggeri pedals were not introduced until 1968, and initially did not have black cages. The Campy Gran Tourismo was not introduced until 1970. I'm also not entirely sure Schwinn was using suicide levers in 1967. And finally I'm not 100% sure the Brooks Pro was available in 1967. It was introduced sometime in the 60's, but I think it may have been very late 60's.
All that said, this bike is worth a lot more than the current $510 bid. Even if you don't believe the NOS claim, an early 70's all-chrome, all original (albeit not for 1967) Paramount in this kind of condition has been going for $1,000 or more for at least a decade now, and I don't expect the recession will have changed that. But the incorrect date does make one question the seller's reliability.
