I am not aware of any Remington .22 rifle with a 672 designation. Unless there is a very late model from Remington with that model number, I believe you are referring to their model 572 rifle. The M/572 was a PUMP repeater that was initially produced in the 1950's, in various grades and is, or was until the last year or two, still being manufactured. Serial numbers were not required on .22 rifles up until December of 1968, when the infamous "Gun Control Act of 1968" was passed. If you do indeed actually have a model 572 PUMP rifle, and you can not find the serial number, you most likely have a unit manufactured prior to 12/68, since all M/572 rifles with serial numbers have them very plainly stamped on the side of the receiver.
