Leather Carrying Pouch for Messkreis?? (May 2022)

This pouch was on eBay the seller listed as ‘Original WWII German transport leather box for aiming circle RK31 1939′.

With markings ‘Wamp 1939‘.

It needs some stitching when received, there are deep scratches at inside, as it was tight fits to the box.  A shaft stand at the bottom of the pouch. Quiet tight to fits in a Messkreis and difficult to put out.

Jointed it together with the leather battery box to became a part of the RK31 Leather Carry Cases set.
