The Yugoslavians also got their hands onto the Sherman. The M-634 was a project using the V-2 engine from the T-34 in the Sherman, the new engine have the Sherman some extra horsepower and speed.

Later the M-634 evolved into the SO-122 which changed the gun from a 75 mm gun to the Soviet A-19 122 mm gun.  The comfortability of the SO-122 is minimal, IIRC it has a whopping -2 degrees of depression.

Mislim da je bilo problema oko hlađenja motora.
