I got both of these 7.92s on a trade with the Israel Army Museum.
Left-Looks like an original loading, GM, 13mm of bullet showing, brass case and primer, green annulus, 70.70mm O/A length, Czech headstamp.
Any idea what loading this could be?
Right-Dummy, GM, 2 case holes. I found this in a “Davidka” mortar round that was adapted to send supplies to beseiged defenders in Jerusalem. Does anyone have the same, or an earlier headstamp on an Israeli 7.92?
