Westmark Gautag 1939, 11 Juni in Trier tinnie WWII German

WWII German Westmark Gautag 1939, 11 Juni in Trier tinnie. This tinnie is in the shape of an elongated rectangle and measures about 1.75” from top to bottom.  The piece is quite handsome, with its alert eagle on a swastika overwatching the Westwall’s dragon’s teeth. The reverse has a vertical pin, which functions fine. The maker’s RZM code “M9/41” appears, with an RZM mark, H.A. Kohlers Sohn G.m.b.H., Altenburg.
