ChKZ mainly produced heavy tanks, and produced limited amount of T-34. From 1942 to 1944, like the later Omsk factory, ChKZ worked as a major repair depot, and I think that the amount of T-34 producted in Chelyabinsk includes the amount of repaired tanks. Considering the American industrial power and the Soviet industrial power, and considering the amount of the T-34 series is significantly higher than that of the M4 Sherman series, I think that the amount of T-34 producted in USSR includes the amount of repaired tanks.
From spring 1943, when the production of the No.183 Ural factory got completely going, ChKZ mainly repaired T-34 and produced only a few amount of new vehicles, I think.
Because, inspecting WWII photos, almost of all T-34 with a rear panel of ChKZ type are camouflaged in white, and they are in winter or snowmelt scenes. And only a few tanks are in summer scenes. (Excluding repaired and used by German army.)
In WWII photograph, in fact, there is no example of having both a rear panel of ChKZ type and a round UZTM turret. (Excluding repaired and used by German army.)
And as long as we can see WWII photos, all tanks with a round UZTM turret have a rear panel of UZTM type and two-separated track that is feature of UZTM tanks. And the road wheels have the characteristics of UZTM - all road wheels are disc type with rubber.
Therefore, as long as we can see WWII photos, in fact, it can be concluded that T-34 with a UZTM turret was not produced in Chelyabinsk, excluding repaired tanks.
＊この作例は、一度説明書どおり塗装完成させたものを、2019年に修正・改造したものです。
This model was built and painted by me along the instruction in the past day, and in 2019 after reseaching T-34 in detail, I modified it.
