My thoughts exactly. Not a fast one. A confusing one but not a fast one. A serial number by Fender is still a serial number by Fender. This has been a really informative thread. Lots of good info cited.
I said a fast one because years later some guy is trying to sell a 75 as a 72 it makes seller look bad when things start coming to light on a place like Talkbass where a bunch of knowledgeable people start throwing up red flags, now let's just assume you are the seller let's say on Ebay this could damage your reputation and you actually going by the neck plate serial# thinking you are not misrepresenting your offer but it turns out Fender just happen to throw a Tele bass neckplate with a # that = 72' on a 1975 bass now your 1972 bass that you most likely paid a market price for that year is a 1975 which would have cost you a much lower price point
