SU-76, Grabin Style

The factory #37 design was far from the only attempt to mount a 76 mm gun on a light tank chassis. Grabin, the man who invented the ZiS-3 in the first place, has his own idea about how to make it mobile.

"Attachment to the IS-10 SPG sketch

This is an attachment to the sketch of an IS-10 SPG, which consists of a 76.2 mm ZiS-3 divisional gun on a T-70 tank. The use of a ZiS-3 in a T-70 tank achieves a powerful self propelled gun with minimal changes to the gun or tank. In the event that higher penetration is needed, the barrel can be replaced with one from a 57 mm AT gun."
