The M4 medium with a welded hull and Whirlwind radial aircraft engine had been the third form of the show to place into manufacturing. Once the war dragged on, numerous changes were built to the M4, the modifications associated with final drive housing, the heavy VVSS suspension system system, different kinds of road tires, included- on armor but the 75mm primary weapon and the 56 degree glacis dishes continues to be un-changed. Until a final version of hull combining a cast front and a welded rear! The kit contains the available spoke road wheels with details right down to the small grease plug, the appliqu armors and the very early M34 weapon mount and M 34A 1 combination weapon mount.
