I found on this Ukrainian site interesting sketched on the LKII tanks, but at the bottom there is this picture of two vehicles appearing to habe LKII chassis but with other construction and armament: http://armor.kiev.ua/Tanks/WWI/kaizer/kaizer5.html
Maybe someone fluent in russian or ukrainian can translate the text regarding this picture.
According to Schneider & Strasheim, the top drawing is of the LK II power limber, Vollmer type. Driver and m-gunner to sit at the front; crew of six in the rear.
