12mm blank Pinfire Cartridge

Size: 12mm blank
Headstamp: GJ [over] 12
Manufacturer: Walbinger, Meuschel & Co. - Bischweiler, Germany
Additional Info: tan wad, After SFM stopped using the GJ headstamp and went to the more common G they allowed some of their subsidies, such as Walbinger, Meuschel & Co., of Bischweiler, Germany to use the GJ headstamp on pinfire cartridges they made. WMC used a larger and impressed GJ and also included the number underneath the GJ, corresponding to the pinfire size.
