Grenade launcher (cup type), for German WW II KAR 98k rifle. NOT SURE IF IT IS STILL IN THE COLLECTION AS IT IS CROSSED OFF THE 1972 - 1978 ACCESSION BOOK LIST. As of 1942, an attachable rifle grenade launcher called the "Gewehrgranatengerät" or "Schießbecher" (shooting cup) was introduced that was developed based on rifle grenade launcher models designed during World War I. The 30 mm Schießbecher cup-type rifle grenade launcher could be mounted on any Karabiner 98k and was intended to replace all previous rifle grenade launcher models. The rifle grenade launcher could be used against infantry, fortifications and light armored vehicles up to a range of 280 m (306 yd). For these differing tasks several specialized grenades with accompanying special propelling cartridges were developed for the 1,450,113 produced Schießbecher rifle grenade launchers. The rifle grenade propelling cartridges fired a wooden projectile through the barrel to the rifle grenade that upon impact automatically primed the rifle grenade. The Schießbecher could also be mounted on the Karabiner 98a, G98/40, StG44 and FG42.
