I've got the movie on VHS and DVD, it is what model companies market as the Ti-67, which is an IDF modified T-55. It is made by Lindberg, Esci and Trumpeter.
The easiest way to tell a T-55 from a T-62 is the road wheels. On a T-55, there is a pronounced gap between the first and second road wheel. On a T-62, the first three road wheels are close together with a gap between the third and fourth road wheels and a real pronounced gap between the fourth and fifth road wheels.
Additionally, the gunner's auxillary sight on a T-55 is hotdog shaped whereas the T-62 auxillary sight is round. This is the port just to the left of the main gun if you are sitting in the turret.
