Gold Wound Badge 1918 on Screwback. Type Wilhelm Deumer, Lüdenscheid (Tombak)

Tombak/brass based and in a very good, barely worn condition with all of the matt gilt plate still present. The high points burnished and all with some slight patina.
Not marked but a known variation that has been attributed to the company of Wilhelm Deumer, Lüdenscheid. On Deumer typical large „clamshell“ screwplate.
Very difficult to find variant.
