Last week I bought this AC 549 7# radiator cap at a swap meet for $1. I bought it for research purposes. It is stamped as follows:
"AC"
"549"
"7#"
"PATD." "794??8"
"2164450" "2?711??"
The patent numbers were very difficult to read because the cap has a lot of pitting from rust.
I suspect it is about the 1956 version because it has the patent numbers. I would appreciate any comments.
