Very attractive medal bar for 4 and 12 year long service medals. 4 year medal shows typical age wear. 12 year medal is much smoother with one spot that looks more like something dripped on it then corrosion. I have a rule against cleaning so don't want to mess with it; Gold finish is really nice on this one. I don't see a hallmark on the rings but I don't want to pull and twist them too much. Ribbon is presented in the classy Bavarian twist style.
