Original 8cm Bipod Leg Lock Spring Replacement

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.These springs mount inside the leg lock knobs and provide the pressure to keep the legs locked into the toothed plate so they don't wobble. These seem to break somewhat frequently and can make the bipod rather useless, as the legs will just flop around and will not lock into any position.Parts are in great condition. Markings may vary; some parts have no markings. Only 3 available - no hope of ever finding more.
