I've got a Browning 16 ga. auto 5 that's pretty old. It has the safety on the front of the trigger guard and the barrel is plain, no rib. The bluing is great (I would say about 98%) and the wood has no scratches, just a few small dents no bigger than the thickness of a quarter. It has the round knob on the butt stock. The serial number is 1232**, and the numbers match. Brownings web site says it was made 1901-1939. Can anyone narrow this down to the exact year? Also, what would this gun be worth? I've dealt with quite a few Brownings, but nothing this old. Any help would be great. Thanks.
