Introduction:
Ostmodels from Tasmania has long been known as a producer of 1/76 resin kits. More recently, Ostmodels also started producing some interesting subjects in 1/72.

Description: (taken from http://panzerserra.blogspot.nl/2015/03/kv-5-soviet-super-heavy-tank-part-01.html
On the 7th of April 1941 the Russian Army set out its revised requirements for the KV-3 and the requirements for two new Heavy Break through tanks, the KV-4 and KV-5.

Work was begun on the KV-5 tank ("Object 225") in June 1941. The talented designer N. Tseits, one of the oldest workers of SKB-2, was named the senior engineer for this vehicle. Also in his group were K. Kuzmin (hull), L. Sychev (turret and gun mount), and N. Fedorchuk (running gear components). The experience gained in the development of the KV-4 design was weighed during the design of the KV-5. The result was a powerful tank of relatively unusual appearance. The hull of the KV-5 had a height of 0.92 metres. Therefore the driver-mechanic and radio operator-machine gunner received special cupolas that permitted them an adequate sector of view. The rhomboid-shaped turret was of relatively large size. Housed in it were the tank commander, who had a commander's cupola, gunner, and loader.

The solid diameter of the ring was 1840 mm and the large internal space of the turret afforded all members of the crew normal working conditions. The tank was heavily armored-150-180 mm.
The KV-5 was too use the same ZIS-6 107mm main gun as the KV-3 and KV-4 but was more heacily armoured with frontal armour of 170mm thick, side armour 150mm and 170mm on the turret.

The vehicle was to also be powered by a single 1200hp engine. Development cracked on during June 1941 and was almost complete in August 1941, but changes had to be made to the hull design as a 1200hp engine was not available, so two parallel-mounted conventional V-2 engines would have had to be installed instead.

By August 1941 the KV-5 design was practically fully completed, and the production of a number of the tank's components and aggregates was begun. But because of the difficult situation at the front around Leningrad, all experimental work at the Kirov Plant was halted and all efforts were dedicated to increasing the output of production KV tanks. The latest date found in the preserved drawings of the KV-5 is 15 August 1941, when the battle was being fought around Luga and Krasnogvardeysk.
The project was eventually canceled in favour of the more advanced Russian heavy tank designs. No prototype was ever constructed due to the Leningrad Blockade . The proposed tank was huge: 11.10m long, 4.00m tall, and weighing 100 tons. The crew of five had plenty of room, but were widely separated. Both the driver-mechanic and the radio operator-machine gunner had separate compartments with their own vision cupolas. The turret was large for its three man crew, with another machine-gun cupola on top for the commander
