the blurb from the Tamiya page says:
When the production of the T-55 began in 1958, a fierce armor development competition ensued between the U.S. and the Soviet Union. Tamiya is proud to present this revolutionary tank as the next addition to the Military Miniature Series. The low clearance chassis has been replicated down to the finest detail, even the cast iron surface of the tank has been faithfully recreated. The characteristic half-sphere turret and powerful 100mm cannon are faithfully portrayed. Not a detail has been spared, even with finer parts such as the engine grill and cast iron wheels.
I'm gonna pick one up (:-)
cheers
