I have an old Mossberg 500-B, 16-gauge, pump-action, 28" full-choke barrel, chambered for 2 3/4. I know this shotgun is at least 30-40 years old and possibly older than that. I'm trying to locate the serial number and am not having any luck at all. Is it possible it never came with a serial number? If it has to have a serial number, where would I find it?
