Scott, I'm sure the guy didn't let you disassemble his dash but I'm thinking a closer inspection of the hole punch might be a tip off as to factory error or later add on. Don't have a reference handy right this second but isn't the factory hole punched not perfectly round and has an offset for the lamp housing?
FWIW my 70 3-speed e does not have the lamp.
Unrelated but my 71 4-speed has the lamp as it should but it seems to have been punched and located in wrong spot on the dash frame. I'm going with the idea that the hole punch guys were
and
at lunch until I can find a better explanation.
