Original WWII German replacement 8cm Gr.W.34 mortar parts. Many parts are still partially coated in a red sealant to provide corrosion protection. The coating is original German also.
This cover goes on the top of the yolk and the elevation screw comes through it.
Parts are in great condition. Markings may vary; some parts have no markings. Only 1 available - no hope of ever finding more.
