I'm having a bit of trouble deciphering these proofs.

Proofed at 1 ton
Then serial number
The stylized R should be a date code but i can't find it in my proofs book
Backwards P with a star is the proofer's mark
The next is the walking lion over PV which means nitro proofed but my books says found in rifles and pistols. Is it also in shotguns after a certain date?
Then the Back Powder Definitive proof
Then 12 ga with 2.75 chambers

Nothing is foolproof to a sufficiently talented fool.
