Sounds like your father in law has a believeable explanation. I don't know myself. I was wondering what years are on the stamps?
Various years from 1958 & '59 (no brand); 1962 thru 66 (Delco).
The stamps are in the form a disk, with the month/year on the outer portion of the disk. You position the stamp over a battery post and whack it with a hammer.
