10/30/18 - From my personal collection (NOT FOR SALE): this item came from the family of the vet who brought it home from the war in 1945-46. It is a piece of glass found in the Walther factory. Not sure if it was damaged by bombing or if it was just broken glass in the trash, but it is marked Walther and Waffen. Also a bit of Oak Leaf, similar to that found on the engraved guns. A nice piece of history.
