Comparing: Pz.Kpfw. IV Schmalturm vs. Type 58

In November 1944 the Krupp company presented several avant-projects aimed to upgrade armament of tanks and tank destroyers in service. Among them there was a project of mounting a Panther's Schmalturm (tight turret) on the Pz IV Ausf. J. The project was canceled due to phasing out the Pz IV production.

The U.S.S.R. exported a total of 1,800 T-34-76 and T-34-85 tanks to China. In 1954 the Chinese government made the decision to begin domestic production of the T-34-85 in 1958, with the new vehicle designated the Type 58. However, production was never initiated, and the Chinese army settled for modifications to the Soviet-made T-34s.
