Well bruv i just happen to be holding a technical manual for the Möbelwagen, Wirbelwind, Ostwind and Kugelblitz printed by the Lodz ghetto printing house 1944 and it says right here in plain english after translation that " The traverse and elevation of the turret was hydraulic, making a full elevation in little over 3.5 seconds, and a full traverse in 8.5 to 10.0 second". But i guess a technical manual dated 1944 and haveing to be translated from german to english is wrong . All this dribble about the turret being hand cranked is false. So wheres the bias?? I can back up my talk with facts can you??
