VK72.01(K) - Pz.Kpfw.VII 'Leichter Löwe'

The VK72.01(K) - Panzerkampfwagen VII 'Leichter Löwe' is based on a Versuchskonstruktion (VK) type of panzer.

In November 1941 it was specified that a new super heavy tank was to be developed in the 70 ton weight class, the VK70.01. In the early months of 1942 Krupp was ordered to start the process of designing this new super heavy tank. 
Krupp presented a conceptual design which was based on the project VK70.01 (Tiger-Maus), armed with a 10,5cm KwK L/70 gun.

The name was changed in April 1942 from VK70.01 to Panzerkampfwagen VII Löwe.

Many alternative designs were considered from February 1942 to May 1942, including rear and center mounted turrets, alternative armament, etc... 
In late 1942 the whole project was cancelled.
The Löwe project never left the drawing board and never reached the prototype stage.

Therefore the rear mounted turret design, VK72.01(K) Pz.Kpfw.VII 'leichter Löwe' armed with a 10,5cm L70 or 15cm L40 gun is fictional. 
Nevertheless I think it is a nice panzerproject to build.
