We have to consider that the whole industry was just taking its first steps. T-35 had so many weapons that the commander could rarely coordinate all of them effectively. This design as ridiculous as it is doesn't surprise me that they actually started producing the tank itself, the whole idea is from the early 1930's so what do you expect
If memory serves me correctly the Allied forces too had this type of tank with two turrets, one mounting a low velocity large caliber gun and the other had an anti tank gun.
