The stock may carry a 72 SN, but probably not fitted to the body till some time later. It wasn't uncommon.

Normally I'd agree, but the odd thing here is that the serial number is on the back of the three bolt neck plate, which Fender weren't making in 1972. But it I a 72 SN. So puzzling, but I suspect just a quirk in the serial number used - Fender Serial Numbers are notoriously inconsistent.
