Comparing: Panzer 58 Mutz vs. Panther mit 8,8 cm L/71

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 a modification of the Panther started in the spring of 1944. The new variant was to incorporate a newly designed Schmalturm turret. The new vehicle was designated the Panther Ausf. F. On January 23, 1945, it was reported that the 88-mm gun of the Tiger was mounted on the upgraded version of the new turret. A large number of hulls for the vehicle were manufactured, but the turret never saw production and existed only as a wooden model.
