Original 5cm Gr.W.36 mortar base plate. This is a ground dug piece but still in very serviceable condition. The thinner sheet metal cup for the cleaning brush is completely gone and the spring loaded holder for the cleaning rod is rusted through. The surface pitting is not very deep and would fill easily to restore. There are even a few spots of original gray paint. This is a really great piece and incredibly rare. Very few 5cm mortars were produced and production stopped in 1943.
