I recently acquired a Remington Model 31 that had no barrel. I know that, based on the serial number (54232x), it is either 16 or 20 gauge but which one is it? I would really like to have a barrel to go with the shotgun I just got.
My question is: how does one know what gauge a Mod 31 is just by the serial number?
