Comparing: Panzer 58 Mutz vs. Chieftain/T95

Developed in 1953 in Switzerland, the first prototype of this tank featured a 90 mm gun. A second prototype with a British 20-pounder gun was built later. In the end, a series of 10 vehicles, featuring 105 mm guns, were produced and remained in service until 1964. After this, the vehicles were used as a basis for the Panzer 61. The only Panzer 58 that survives today features a 20-pounder gun and is currently located in the tank museum in Thun, Bern.

Development of the FV4201 Chieftain allowed for the interchangeability of guns with the U.S. T95 tank by means of exchanging turrets. The project was discontinued because of numerous problems with training crews to master two artillery systems.
