1936 is, IMO, a bit too early for this vehicle, even 1937 is pushing things. I'd be happier with 1938-39, but I understand the way things are creeping. Also, if your crew is laid out the way the text claims (commander, loader, gunner, driver) you're going to need a larger turret than the T-34/76 had and the front hull MG has no one to operate it. The correct crew layout would be commander, gunner, driver, radio-operator/front hull machinegunner.
