Comparing: Pz.Kpfw. IV Schmalturm vs. T-34-85M

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.

A modification of the T-34-85 tank, produced at Factory No. 183. Unlike the original vehicle, it featured enhanced front armor and reduced rear armor. Fuel tanks were transferred from the fighting compartment to the rear. When the suspension proved faulty, production was halted after just one prototype was built.
