K-91 Version II historical reference
A variant of the K-91 with the frontal placement of the turret. This vehicle was developed by the Design Bureau of the Army Engineering Committee under the supervision of A. F. Kravtsev from March through August 1949. The plan was to mount the 12-cylinder opposed-piston supercharger diesel engine. Mounting brackets with ski-shaped supports were used as support rollers. The development of the project was discontinued at the blueprint stage in December 1949.
