Need help finding serial numbers!
My cousin and her family just had their gun collection stolen. However, those guns had serial numbers. My cousins husband just got two new 20g shutguns. One a Steven Savage pump and a Mossberg bolt action. All they have are model numbers and a couple small stamps/markings that I can only imagine are factory markings. Is it possible that serial numbers weren't around when these were made, or are the model numbers the serials? I have no knowledge of this and they are wanting to get as much information on them as possible in light of the recent break-in. Any help is appreciated. I thought of ya'll first Apaches!
Stevens Savage 20g
Model 77D (cousin cannot find this model on internet)
