The city of Leningrad was the home of the KV, having been designed and built at the Leningrad Kirov Plant (LKZ).
So during the late summer and fall of 1941, the KVs were seen in action more often in this sector of the front, having been driven straight from the factory.
In fall of 1941, three tanks, freshly repaired, are on their way from the rpair shop parading through Palace Square with the Alexander column.
The lead tank carries the slogan "We defend the conquests of October" referring to the October Revolution that put the Bolsheviks in power in 1917 which took place from Palace Square.
This tank is a KV-1 Model 1941 with the new uparmored welded turret recognizable by the short rear overhang.
It is a mixture of the old F-32 main gun of Model 1940 and new road wheels.
The tank behind it is wearing the slogan "For Stalin" while the last KV is decorated with the ubiquitous "Hit the Fascists".
