I got hold of a couple of resin kits of the Russian T-100z in Taiwan. Not sure of the make but I think it is a pukka kit rather than a knock off as the quality is quite good (not up to Atelier Infinite standard but still a good quality kit).
Here is some bumph I found on the tank and its development history:
The T-100 was a twin-turreted Soviet heavy tank prototype, designed in 1938–39 as a possible replacement for the T-35. The T-100 was designed to by N. Barykov's OKMO design team at S.M. Kirov Factory No. 185 in Leningrad. It was in competition with a similar design - the SMK - but neither were adopted and instead a single turret version on the SMK was ordered as the KV-1.
The prototype T-100 tank was briefly tested alongside the other designs in the Soviet invasion of Finland in 1939 without success. It was never put into production, due to the archaic design concept, poor mobility and the availability of a far superior alternative, the KV series.
There were attempts to use the T-100 chassis as a platform, with one being for an 6in howitzer carriage (T-100Z).
The tank has an insanely high profile so no hiding from the enemy! At the end of the picture as some comparisons with other Russian tanks to give an idea of size.
KV 1 comparison:
T35 comparison (the T35 is the Panzer Depot one with a wash and mud applied):
and finally a comparison with the KV 5:
