Original Item: One-of-a-kind. This is a genuine German WWII Foreign POW Identification Tag  (aka; Dog Tag) or Erkennungsmarke. The badge is made of zinc in very good condition, with just a bit of oxidation.

It is marked on each half as follows:

This is the abbreviation for Kriegsgefangener Lager Zeithain, or Prisoner of War Camp Zeithain. This was a subcamp of the very large Stalag IV-B Mühlberg, made specifically to accommodate Soviet POWs. The camp, originally known as Stalag 304 (Stalag IV-H), was built in April 1941 next to the military depot, training ground, and Jacobsthal railway station, to accommodate Soviet prisoners. Many of the prisoners were sick, and the close quarters allowed Typhus and Tuberculosis to run rampant for years, resulting in many dead prisoners. 

In February 1943 Zeithain was transformed into a hospital camp designated Stalag IV-B/H, and after the transfer of doctors, nurses, and equipment, hygeine was improved, and this was the only German POW camp to house both male and female prisoners.
