I think a potential buyer will discount the parts that are younger and look at what could be reasonably correct, the wheels are "wrong" the hubs might be correct if they are not stamped Record, the rear derailleur is wrong, maybe the front, and the pedals, those are the big easy to see items.

Most of those parts do have value to help offset making it correct, but it makes for a project for the potential buyer, as a rider they are fine, and I would probably leave them save the rims, but that is just my personal view.

$1,500 is probably tops as it is, if there are two guys bidding against each other for it, as a offered price it will be below that most likely.

Makes me want a black bike again, they look soo good when clean with bright bits...
