BTW, if anyone knows, I'd appreciate knowing what the grace period after
expiration was in 1975 (I was told by a field-office rep that my expired
Advanced couldn't be renewed and later I was told that I was probably
misinformed and was within a grace period, but I could never confirm that
fact).

I thought it was 2 years but it never affected me so I'm not positive. The
upside is you can probably go get a new one with a weeks worth of brush-up.
