Footnotes

1. 3,7cm Kw.K., 3,7cm Pak 35/36 and 3,7cm Pak 162(i). Source: Jentz, Thomas L: Tank Combat in North Africa; Chamberlain, Peter and Doyle, Hilary L.: Encyclopedia of German Tanks of World War Two; von Senger und Etterlin, Ferdinand Maria: Die Deutschen Panzer 1926–1945; Haupt, Werner: Panzer Anklopf Kanone and Hogg, Ian V.: German Artillery of World War Two. The barrel length is sometimes given as L45 instead of L46.5. Jentz refers to the anti-tank gun as Pak 35 instead of 36, in some other references it becomes the Pak 35/36. In an effort to find the correct name Claus Bonnesen sent the following information to me: “I found another reference to the Pak 35/36 in the guide book for the Panzermuseum in Munster, so I suppose the nomenclature could be like that… The 3,7cm Pak started out in 1928 as the 3,7cm Tankabwehrkanone looking very much like the World War II gun, but with steel rimmed, spoked wooden wheels. Intended to be towed by a horse, it was rebuilt for motor towing in 1934, receiving new steel wheels with pneumatic tires and a suspension. It may be that the Pak 35 was the one with wooden wheels and the Pak 35/36 the one with pneumatic tires and that common usage boiled it down to either 35 or 36.” The Pak 35/36 was sarcastically nicknamed the Panzer Anklopf Kanone (tank tapping gun) in 1941 after it proved incapable against the Soviet T–34 and KV–1 tanks. Although Hogg gives the maximum effective range of the Steil.Gr. projectile as 300 metres, Haupt states that the scattering was very great at distances over 200 metres, so this is probably a more realistic maximum effective range. The 3,7cm Pak 162(i) was an Italian licence built version captured by the Germans in 1943 after the surrender of Italy. They were used by some second line units and some were installed in the fortified lines across Italy. (Partly from On Armour by Claus Bonnesen). [up]
