12/16/20 - This is a scarce panzer tank badge awarded for 50 engagements / assaults. This two piece medal is in great condition with some light patina. The reverse of the medal is "GB" maker marked. The rivets are hollow, as shown in photos. In Michael Tucker's book "Collecting Military Badges of the Third Reich", this style of rivet is attributed to C.E. Junker and GB makers. So this is correct and original.
