The barrels are marked 12B and 13M (seemingly indicating a 12 bore), but a modern 12 gauge shell seems loose in the chamber (although it does seat properly).

Does anyone know anything about "oversize" 12 bore Greeners from this era?


The 13M indicates muzzle diameter or choke. I'd get that top lever screw timed.

With that done I'd say it would have a value of $1000.00 to $1500.00 depending on who was buying or selling.
