Alternator markings

Wondering about the numbers above the part number on the 37A alternator? It's not an assembly date code, that is stamped below the part number. Anyone knows?

Agree, you are correct. But I am curious about the 2-2-3 on top? Have never figured out what these numbers mean...

nice site but incorrect in at least one pic.



this is not 72 and late alt... is an EVEN LATER piece, 76/77 and lates piece. 72/76 are with brushes disposition still 90º like roundbacks and using same isolators. The 76 and lates brushes isolators changes one of them. case is totally diff too and is wider
