Good Afternoon Everyone:
My buddy at work has a Browning BAR 30-06 made in 1967. We are trying to figure out what the stamped 'proof' marks mean. Does anyone have any knowledge? We are just trying to learn more about what seems to be an early production rifle. The serial number is 3466 M7. I assume my 1969 BAR has similar markings, but I have not checked it yet.
Thanks in Advance!
Costanza
