On November 22nd of 1942, Hitler approved the production of a single Rammtiger - barricade and obstacle destroyer. Porsche completed the planning stage by December 7th of 1942 and on January 5th of 1943, Adolf Hitler decided that three VK4501(P) chassis are to be modified and converted to Rammtiger / Raumpanzer Tiger(P). This lightly armed (with MG) vehicle was to be a standard VK4501(P)'s hull mounted with streamlined upper superstructure and front mounted plow (ploughshare). The streamlined shape of the superstructure would allow the rubble to slide off the vehicle. In May of 1943, three superstructures were completed and three Rammtigers were ready in August of 1943. Their fate is unknown after August of 1943, but it is unlikely that they saw any combat and probably remained at Nibelungenwerke. Other sources state that only 1:10 and / or 1:15 scale model was made when the entire concept was rejected and three chassis were used as previously planned. http://www.achtungpanzer.com/tigerp.htm Something like this... http://www.mf-panzermodellbau.de/rammtiger-front-li.jpg
