SMGP-0129 German communication artillery medal /tinnie

Ive never seen one of these before to be honest. It’s aluminum and tinnie sized but lacking a pin and the Ges Gesch mark is right in the middle so i don’t think it is supposed to have one. The medal depicts an urban scene with one solider directing signals with paddles and two more men in a blown out building working a communication radio set up. Very neat war scene that is uncommon on tinnies and medals.
