The first
MMs delivered were largely similar to the
GAZ-AA »Polutorka«, differing only by the rear sparewheel mount which became optional in later versions.
In 1941 however, Gorkiy Auto Zavod (»GAZ«) developed a simplified version by adding angled fenders and cutting out the cab sides.
They increased the engine power to 50 hp and modified the cargo platform as well.
This model version stayed in production throughout 1942.
In 1943, another modification took place by reclosing the cab with wooden sides, resulting in the model 1943, shown here on the top and bottom of the page.
As with the
GAZ-AA, the
MM delivered the base for countless variations.
