That tank looks like before running back to Muti, the Germans stuffed the thing in a leaky barn, and it was found years later..

Great weathering. In my 1/32 tanks I used to weather quite heavily, but always wondered :”would a good commander let his tank go this bad?” ... and went-on adding more rust and grime..

By the by, did the gearbox come with a 550 motor, or is that a later addition?
