Thanks guys, it seems these K.V's must still be covered by Iron Curtain secrecy...ha ha! I have a few reference pics of the exterior and the etch brass fenders, metal tracks, ali-gun barrel etc. Just short of how to fill that huge steel coffin of a turret.
Thanks for the details of that book adam, it's one I will be investing in i think but i will drop you an e-mail next week once yours has arrived. Since most of my reference stuff is of WW2 German vehicals arms and uniforms, if you or anyone else need any help in that area, please just ask.
