Early manufacturer examples such as this are increasingly sought after by collectors due to their age and relative scarcity compared to mass-produced WW2 rounds.\u003c\/p\u003e\n\u003cp data-start=\"1089\" data-end=\"1358\"\u003eThis round is completely inert and safe for display, retaining its original brass case and bullet.
