Ihad the luck to get a fine Dumoulin round action sidelock gun from Li�ge maker F. Dumoulin & Cie. What I find especially remarkable is the year of proof: 1943 ! That was in the midst of WW II, Belgium was occupied by the Germans and the production of fine guns probably was down. Nevertheless this gun is a nice example of Li�ge artisans. See more:

Very Nice looking gun, but what is your definition of a "Round Action". That is not what I would call a round action. It appears to be sculpted with rounding at the front, but all I have ever seen on a round action had the action bottom rounded all the way back to the wood.

@2-piper: well, it's not alone my definition, Holland & Holland seems to call it the same way:

maybe the Dumoulin is a little bit less rounded...

Very similar engraving to a Doumoulin side by side 12 bore trap gun that I have. Oddly, mine too was made during the war around the same time; serial number 62444. A boxlock I have; similar period, 80135. Well made guns. Lagopus.....

Interesting, thanks! What steel are the barrels of yours?

If you compare the H&H with your gun you will see it has a totally different shape to the action. The H&H has the bottom corners of the action rounded All the way back to the wood, this gun does not. There is no sculpting at the front of the bar on the H&H, it has essentially the same shape for the entire length of the action body. The H&H has a back action lock so the mainsprings do not lie in the frame bar. This Dumoulin from the pics appears to be a bar action. It would be I believe rather difficult to make a round action using a Bar action sidelock. Most round actions are either a trigger plate action or back action sidelock.

Understand I am not knocking your gun because it is not a round action, I have never owned a Round Action Double. I have several with a similar shaped action to this one though not of the same high quality. I just do not see it as being classified a Round Action.

I believe Steve Barnett has offered a Dumoulin once or twice with a rounded action. It looks much like Gunwolf's gun . Compared to "normal" Dumoulin sidelocks, this action has rounded edges . I would call it a rounded action. See Steve Barnett's "round" action Dumoulin.

As to the date mark, I ,too, have found a couple of guns from the mid to late 40s proofed. Those trying times must have had special rules, but I don't know what they were.

Gunwolf, it doesn't say on the sidelock but the boxlock says Poldi Nickel Steel. The engraving on my sidelock looks as if it may have been done by the same person as yours as it is strikingly similar. Lagopus.....

Perhaps the picture is giving an optical illusion. I see the frame as it surrounds the bar portion of the lock as being a flat surface. Every thing behind thar forward sculpted section looks to have a perfectly Square (L) corner to me. "IF" I am not seeing the picture correctly do enlighten me. Look at this picture closely & then look at the one in the H&H link, I believe anyone can see the difference. Call it what you will, but I don't call a square, sharp corner Round.

@2-piper: I`m not offended with your opinion on the gun! It doesn`t matter, how one calls it. The corners of the action are rounded, not sharp. May be one cannot see it...

If you look here, they call it "Boss style round action": http://www.gunsinternational.com/guns-fo...un_id=100973747

I think, it's nearly the same as with my gun.
