Comparing: Panzer 58 Mutz vs. M4A1 Revalorisé

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.

In the 1950s, the M4 Sherman of various modifications was supplied to France as part of MDAP. French design bureaus started modernizing the vehicle with the goal of improving its firepower. This initiative was followed by a modernization program for the Israel Defense Forces (Sherman M51). The tank never saw service in France. The number of prototypes built is unknown.
