Quick question for you gun experts. My father in law has a old ancient Stevens Savage 1500 shotgun that he had when he was younger. Best guess is that it's circa mid '40s. Looks to be in really good shape, been in a bag since 1964. Any idea if it's worth something? He said he didn't want it, and was just going to turn it into the police, but I thought we should check to see if it's worth anything to a collector.
