A captured document dated January 1942 refers to the introduction of a
new antitank gun, the 42-mm Pak 41.
Examination of ammunition recently captured in the Middle East shows that this is
a tapered-bore gun, the barrel tapering from 42 mm. at the breech
to 28 mm. at the muzzle. Both HE and AP are fired, as in the case of the
earlier 28/20-mm antitank gun, Model 41.
In this new weapon, it is interesting to note that the Germans are persevering with
the Guerlich principle of a tapered bore.
