A fine original WWII German Krimschild (Crimea Shield) here, unfortunately without it's backing plate and felt. Two full prongs remaining on the reverse. Appears to be bronze/tombak construction. Some discoloration/patina is visible on the front of this shield and depicted in photos. Strong details.
 
The Crimea Shield was a World War II German military decoration. It was awarded to military personnel under the command of Field Marshal von Manstein, including supporting naval and air force units, who fought against Soviet Red Army forces between 21 September 1941 and 4 July 1942 and who captured the Crimea region
