The design was first used in the Polish 7-TP light tank. Shortly before the war it was given to the British and was used in almost all tanks of WWII, including the British Crusader, Churchill, Valentine, and Cromwell and the American Sherman. After the German and Soviet attack and fall Poland in 1939 it was copied entirely from captured 7TP and TKS Polish tanks and used in all 1940 and later tanks of the Germany (including the Tiger) and later by USSR (including the T-34 and T-70).

  • The design was first used in the Polish 7-TP light tank. Shortly before the war it was given to the British and was used in almost all tanks of WWII, including the British Crusader, Churchill, Valentine, and Cromwell and the American Sherman. After the German and Soviet attack and fall Poland in 1939 it was copied entirely from captured 7TP and TKS Polish tanks and used in all 1940 and later tanks of the Germany (including the Tiger) and later by USSR (including the T-34 and T-70). As a part of Polish-British pre-war military cooperation, the patent was sold for a penny (actually 1 Polish Zloty) to Vickers-Armstrong. It was produced as the Vickers Tank Periscope MK.IV (pictured), and built into all British tanks (Crusader, Churchill, Valentine, Cromwell). After the fall of Poland, Germany, USSR and Romania captured some equipment, allowing them to copy the invention. In USSR the Gundlach periscope was known as MK-4 (harking to the British designation, as Russian sources openly confirm that it was copied from samples acquired with British-supplied tanks) and implemented in all tanks (including the T-34 and T-70). All Axis tanks and APC (including tanks of Italy, Romania, Hungary, Finland and Japan) were equipped or retro-fitted with this periscope till 1941. Later technology was transferred to USA and as a periscope M6 implemented in all US tanks (M3/M5 Stuart, M4 Sherman and others). At the end of WWII this technology was adopted throughout the world and used basically unchanged for almost 50 years, until it was replaced by eletronic devices.
