Hey all. I have recently acquired what looks like a Browning auto 5 with a date code of "d" which means either 1925 or 1965. I was told by the previous owner that it had been in the family since 1925 BUT the shotgun also has a controller of proof codes mark of "H*" which seems to only have been used from 1938-1968. BUT the serial number of 73XXX puts it pre WW2. This confuses me. Also, did John Browning allow FN to make the A5 and market and sell it as an FN gun in Europe? The name Browning only appears in the patent information. Aside from that, Browning appears nowhere else on the shotgun. Thanks in advance for any help y'all can give.
