hudavendigar, the M44T looks great. Did the modifications include a new engine and a roof? The original M44 sure needed a more fuel efficient engine.
More fuel-efficient diesel engine instead of the original gasoline engine. Result was about five times increase in the vehicle's range.
More compact engine: Driver moved from the left on the superstructure to left at the front in production vehicles. Some modifications to the front part of the superstructure.
L39 gun instead of the original L23: Result was about twice increase in gun range with rocket-assisted projectile.
Upgrades and automation in many subsystems and tracks.
Dust skirts were added.
Roof remained the same: Open top with tent. Enclosed turret was that of M52T.
