Emhar MkIV Tadpole WWI Tank with Rear Mortar To thwart the new British MkIV Male and Female tanks the Germans dug wider trenches. In 1917 trial modifications to improve trench crossing ability began. The 'tadpole tail' extended the rear of the tank by about nine feet. Angle iron cross-braces were fixed between the 'tails' to improve rigidity. On one experimental version these provided support for a steel plate on which a forward firing Stokes mortar was placed. Many Tadpoles were planned. Initial conversion trials were carried out in England and tail assemblies were sent to France. Problems with the conversion were not overcome by the end of the war and Tadpoles were not used in action. No markings are known (hence no decals are included in the kit). Tadpoles did not have de-ditching rails and the exhaust was shortened.
