The SN is FWR 49XX which I think makes it 1919? The barrels are 26" with the left stamped MOD.
It was his step father's gun and came with both
2-9/16 and 2-3/4 shells. My depth caliper shows the chambers are short of 2-3/4. Is it possible that obsolete 2-3/4 shells were OK in this shotgun?
Thanks in advance for any info - Rick
