It's very confoooooozing Tex. One place says this.....the other says that. Blue Book says one thing, Proofhouse says another.....???????
Here's what the Browning Co. website says.....
"1903-1939 First 10,000 shipped to U.S. Marked with "BROWNING AUTOMATIC ARMS CO. OGDEN UTAH-U.S.A." Very few serial number records remain. Beginning with Serial Number 1 to approximately 228,000. Exact production figures are not available. Year of manufacture on Pre-World War II production is strictly a guess." http://www.browning.com/services/dat...tail.asp?id=13
Soooooo.....believerjoe....welcome to TFF and welcome to the confusing world of trying to date guns by their serial numbers!!!
Your shotgun is most likely a Browning A5 that was probably, possibly, maybe, made between 1902 or 1903 and 1939 and came to the U.S. some-how-or-other.
In any case, you have a wonderful, beautifully-made shotgun, designed by the greatest firearms inventor who ever lived (even Tex will agree with me on this!), John Moses Browning.
