In the early 60's, my dad paid a guy $40.00 for what I always thought was a Browning 20ga semi-auto. Just a couple of days ago, I began trying to find out more about the gun. I had no idea that Browning never actually manufactured guns. I contacted Art Isaacson of Art's Guns and Sport, Inc. (artsgunshop.com) in Hillsboro, Missouri. He emailed me and said the gun is an American Browning that was made by Remington during the WWII years; 1940-46. Mr. Issacson told me the gun is actually more of a Remington than a Browning. When I first started researching the gun I discovered all of what I know and that's been in the last few days. But I wanted to reach out to you guys as well to see if anyone else knows much about the gun. There are several stamps on the barrel. Would anyone have any idea about the meaning of the stamps?
