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

H is the year code and that is 1929
Q is the controller code and not shown who that is for 1929
Barrels weighed 1.437 Kg in the raw

The way the proof is laid out is like a set of Parker barrels I have that were made in Belgium by Armaf Dagun in the 1950s. Contoller code Q is for Dewild Gaspard who worked 1952 to 1968, I wonder if the year code is a Greek letter (maybe rho) which would be 1958, note that it also has 70mm chambers.

Thanks skeettx. I would never have read the h and q without help and I was not looking at the kg which is correctly weight not tons pressure.

Interesting looking

Controller's (inspector's) marks can not reliably be used to date a gun; they were re-used and the significance of many has been lost to a fire at Banc d'Epreuves de Liege . I believe PeteM posted the fire was in the 30s.
