I don’t think it’s very rare or valuable but I’ve loved humpback shotguns since I was big enough drool into a shooters bible. I’m going to see if I can cut some grouse and quail feathers with it this fall. Savage 720.
I’ve never seen a Savage built on a Browning patent. Do remember a Remington though. I hunted with one a buddy had. He got hard up for money and sold it to a gunsmith for $35. Yeah I was disgusted.
