MG42 soaking can marking bdk 4

German machine guns were commonly supplied with soaking cans for muzzle components the make cleaning easier. The soaking medium was kerosene, referred in the German literature as Petroleum. The practice went back at least as early as the MG 08-15.  The mg42 soaking can was designed to hold the recoil booster assembly, which consists of the flash suppressor, recoil booster housing, and recoil booster cone. Rare piece for the MG42!
