This is an ultra rare WW2 German 1942 dated 2.8cm Schwere Panzerbuchse 41 (28x187R) squeeze bore armour piercing (AP) round, Although this gun was called an anti-tank rifle, it was in fact a small piece of wheeled artillery intended for use by the German Fallschirmajeger (parachutists). The gun had a tapered bore on the Gerlich principal. The projectile carried two external flanges, as it proceeded toward the muzzle, the flanges were squeezed down, decreasing the diameter with the result that pressure did not drop off as quickly and the projectile was propelled to a higher velocity, the compressed air between the front and rear driving bands being vented by the 5 small holes in the front driving band. The guns bore tapered from 28mm at the breech to an exit diameter of 20mm. The original diameter of the 28mm projectile consisted of a flanged skirt with air bleed holes on the front steel driving band and a collapsible rear driving band. This round consists of a bottlenecked rimmed case which is headstamped avu 4e 2,8cm Ptrh.PzB 42 (1942 date) WaA73. The cartridge case is fitted with a steel percussion screw in percussion primer. The steel squeeze bore projectile is fitted with a tungsten core and has 5 small air venting holes in the front collapsible driving band and is stamped round its circumference aux (Polte-Werk, Magdeburg) 2g41 WaA109. The nose of the projectile is fitted with an alloy ballistic cap. The production of this gun was discontinued in 1943 due to the shortage of tungsten for the armour piercing projectile.
