But the Panther was a response to combat on the eastern front. How can the Germans get it before that battle starts?
The real issue where characteristics the T34 had that were useful. Sloped armor, wide tracks with large road wheels and a long, high velocity gun.
Let's argue the Germans realised all this pre-war and built something a little larger (30 to 35t) than the PW4 with these characteristics.
The Soviets were thoroughly into the mixed infantry-cruiser armor concept pre-war like everybody else and learned the error against the Fins. But the T34 was originally conceived as a "tank-hunter". The question would be what if the Germans also conceived of a tank-hunter pre-war.
Most originally believed that HE rounds from the low velocity guns would be adequate anti-armor.
