Terry,
It is very unlikely your gun was made in 1941. Germany was occupying Belgium. Sporting firearms were not being produced in any numbers, as the Germans had the Belgians making parts for their military needs.
I would suggest the gun was made in 1961 instead.

Nice gun.
Not sure what you want to learn about the Dumolin name. They were around from 1830 to at least 1968. Their office location changed several times during that span. They also maintained an office in London at 9-11 Wilson St around 1897 or so. (Perhaps supplying parts to the trade?) To add confusion, there were Dumolins working in Austria, Portugal and maybe France.
They are one of most difficult names to deal with. 1st, it appears every one in the family was a gun maker, at least in name. Second, there seems to be some indication that they would put a Dumolin name on a gun, even though that particular Dumolin had no part in its manufacture.
At 1st glance there was F. Dumolin & CIE and also Dumolin Ferres. In addition there were at least 15 other Dumolin names registered. Adding to the confusion there were the hyphenated Dumolins, Dumolin-Demarteau, Dumolin-Paques, Dumolin-Labinon, Dumolin-Gerard, Dumolin-Rossels & Dumolin-Colombier.
The earliest Dumolin's seem to have specialized in converting flintlock guns to percussion. Over the years, various members of the family formed working relationships with Waranant, Remington and others. They produced just about every imaginable type of firearm.
Apparently some did hold patents, though I have never seen a master list.
In 1898 Neumann Freres, Janssen fils & Cie, and F. Dumolin & Cie formed Syndicat des Pieces Interchangables. This was done to standardize the manufacturing tolerances of sporting arms. Shortly after forming, they turned it over to Fabrique Nationale. Not surprising as many of them had been founders of FN.
Dumolin really should be viewed as a major player in the Belgian gun trade along side Pieper, Francotte, Heuse, etc.
