Elliot,
At the time of proof the barrels weighed 1.334 kgs or 2.94 pounds. If they are much lighter than that, some one has messed with it. It was proofed for nitro between 1910 and 1924 from the proof marks. Given it has Edouard's trademark, we narrow the dating to pre-WWI, so between 1910 and 1914 or so.
The regina trademark was registered by Edouard Schroeder in 1903. He was located at 4 rue Renoz in Liege.
Edouard had 2 sons, Charles Edouard and Max. They established their business 1919 at 26 rue des Comediens in Brussels. Whether or not their father survived the war is unknown, but he no longer was making guns after 1918. In about 1919 they registered 4 trademarks of their own. Being in Brussels took them out of the still crowded Liege market and set them up to deal with larger and more influential clients. In fact, it may account for the firm surviving WWII.
The firm survived the brothers and was in business until 1966. As such, they had a long history in the gun trade. For a time, they were general agents for FN. As such they sold Browning o/u, Zeiss optics, cartridges, swords, muzzleloaders (meant for the African trade), reloading equipment, pistols, rifles, etc. This is from a 1930 catalog. I have not seen a catalog from Edouard.
As for value, the only thing this gun lacks is name recognition. From the pictures, it is up there with some of the better makers of the day.
