M3 Lee / Grant Tank Series in Soft Metal

This is the M3 Lee tank.

The US Army used the M3, M3A1, M3A2, M3A3, M3A4, M3A5 and M3A6 tanks in WWII, and the M3 Grant.

This model by Revieresco and several other kits them make can be combined to make at least 20 different sub-versions of those tanks.

 This particular one is actually the welded hull version with gasoline engine.  There is a also a diesel engine version.  They used three different guns, different ventilators, and different side door configurations, and much more.
