Raimey,
It looks like a Meffert to me.If I'm wrong, it's not the first time. I doubt that you can count on guns made by Meffert for someone else to be in their serial number range,I could be wrong.The link you gave doesn't give the answer. The 6mm Flobert didn't require a liscense, but the .22lr did.Anyway,the gun in question had the case length, for the barrel in question,shown as 35mm. The cartridge has to be 5.6x35R Vierling, which wouldn't fall under this. They didn't use the ga.designation of bore diameter with case length, as a general rule.Ga.designation of bore diameter stopped and case length stamp started in 1912. This gun was proofed considerably later than this.(Mauser did mark their .22s with the ga. in addition to 22 lang fur buschen, until the war.)
