This is a private purchased WW2 Miniature Silver Marked A.R.P Lapel Button back with Original Pin Backing. This example is not your normal ARP badge this is a miniature example made privately and purchased privately. These are a lot more desirable and unusual compared to the larger more common examples. This example is in very good condition with only minor wear. It is marked sterling silver on the rear as you can see. Please see photos for condition.
