Hmmm,... I'm not too sure I'd agree with all of this (but the bit about the fixed seats in the T34 is spot on), The T34/M40, M41 and 43 models had an electric motor that could spin the turret 360 degrees in roughly 14 seconds (but the turret control did not allow for fine adjustments, thus the gunner need to switch to hand operation, the T-34/85 also had an electric motor but took about 21 secons.

On the German side we have the have the problem that turrets were more often than not completely out of balance and thus made power 'training' (using the motor to zero in) almost impossible

Pz IV - Electric motor; 25 seconds
Panther D - Hydraulic motor; 60 seconds
Panther G - Hydraulic motor; 18 seconds
Pz IV - Electric motor; 25 seconds
Tiger I - Hydraulic motor; 60 seconds
Tiger II used the main engine to drive its hydraulic motor but it came at a cost - Hydraulic motor; 10 seconds @ 3000rpm but this could damage the engine, or 19 seconds @ 2000 rpm

Sherman and Pershing came in at around 15 seconds, while the British Crusader could traverse in 10 seconds, Cromwell in 15, Comet in 24.
