Actually, there's a funny story in that regard. As a clause of the Molotov -Ribbentrop Pact, Germany agreed to show the Russians all their tank factories and stuff. So when some Russians came to visit, Hitler told his people to show the Russians everything. However, when they Russians were shown the Panzer 3 (or 4, I can't remember), they kept insisting that the Germans weren't following Hitler's orders, since they must have a heavier tank. Come Operation Barbaross aand the appearance of the T-34, the mystery was solved.
