🇩🇪German '10.5 Geschützwagen Mk.6 (e)':

Created in WW2, the 10.5 cm leFH 16 auf Geschützwagen Mk.6 (e) was based on a captured British Mk.6 light tank and would be converted into a self-propelled howitzer.

The main armament would be a 105mm Light Field Howitzer 16. The base 88hp Meadows 6-cylinder engine would remain unchanged and the added weight would reduce the top speed to 50km/h.
