Hi,

as I am quite new to the world of hunting and firearms I was wondering if someone more experienced could help me figure out roughly when a shotgun I acquired was made.

It is a Belgian side-by-side, 12-gauge shotgun, by Pieper/Bayard, but that is about all I know about it. It is in an okay working-condition, but I doubt it would ever win any beauty contests.

I would be very happy if anyone could say anything about the year of production based on the photos provided.

Thank you all in advance!

Press in the button and pull down on the forearm with the gun closed. One hand holds barrel set while you work the lever to open the gun. The barrel set will come off in your hands, thus the caution to hang on to them.

After submitting the question here, and getting the rather indispensable tip to check for markings beneath the barrels(thank you Mr. Hause), I stumbled across this rather excellent thread upon the subject:


From this I ascertain that this shotgun is made pre-1968(based on the crowned ELG-mark). But it seems I have to do some further reading in said thread, or rely on further assistance form the fine folks of this forum to get a more eccact date.

I thought it would have a lettre annale but it does not and was manufactured 1910-1921
Above the 20.7 should be the chamber length; 65 or 70
It does carry Smokeless Powder proof
At the time of proof the barrels weighed 1.553 Kg = 3.42#. If > 3% less now (from honing) the barrels are considered out of proof.
The bore at the time of proof was 18.2 mm = .717"
The R muzzle constriction at the time of proof was 18.0 mm = .709" = .008" or IC
The L muzzle constriction was 17.4 = .685" = .032" or Improved Modified

Have a double gun specialist with the interest, expertise and tools (wall thickness gauge and bore scope) evaluate the gun then enjoy :)
If the chamber length is illegible the smith can measure for you, and should confirm the choke measurement.

Thank you so much, I really appreciate all the help! Turns out this was far older than I first imagined, seems like I am in possession of a century old gun then, go figure 😄

Thank you, that's a great tip!

The local gunsmith where I bought it did a quick inspection(I guess he wasn't overly interested in the history of the gun) and did a couple of test-fires. I got some ammunition along with the gun, but I'll have to wait until morning(it's getting quite late here in Norway) to check what kind of loads they are.
