What if the German spies had accessed the blueprints of Bob Semple tanks in New Zealand and are impressed as how they could possibly consume less fuel since that's what Germany lacked during WW2 and as a result, the Germans then mass produce the tanks and use it for the invasion of the Soviet Union in June 1941. What would happen with the Germans invading the USSR with 500,000 Bob Semple tanks? How would the war last? What would Hitler do?
