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 piece hides inside the cross level mechanism and acts as the part the threaded rod pushes against.
Parts are in great condition. Markings may vary; some parts have no markings. Only 1 available - no hope of ever finding more.
