Nubie here trying to figure out the serial number on my A5 The receiver has 8V 6472, the barrel has 6274. I have a hard time believing they aren't original to each other. Think they just reversed the 2 and 4? Also, I know this is a low number so no records of date? Also, as stated on Brownings website, it doesn't have "BROWNING AUTOMATIC ARMS CO. OGDEN UTAH-U.S.A. stamped on it. Confused please help. Also, THANK YOU in advance for your help!
