Re: H&R 1908 shotgun barrel marking
It has all the characteristics of the 1908 - as you state. I have never seen those markings???? Are they in plain view or hidden by stock? FROM the s/n and pure speculation at this time, I'm thinking your gun was made after 1920 or so, maybe closer to 1930 and should have the 2 3/4" chamber.
Please post a pic of the "flat sides of the receiver" and the "round curve back by the hammer". Fixed hinge pin, with snap off forestock is 1908 standard.
Just a thought - the HPR may indicate factory proof on guns meant for export to British Commonwealth importers???????????????? As I stated just earlier today, I was able to find info indicating that H&R was licensed by England to "in-house proof" guns meant for export to them and theirs, without point of destination reproof. Would be interesting if that should proove to be true.
