Some time ago I saw this badge on ebay. It was described as a replica of an unknown badge, so no help there. I really like the dark green enamel and overall
appearance of the badge, probably because I love all awards and badges which depict industrial facilities (odd, I know. I really have no idea why I like them so much ). Well, this one really got me but I wasn't able to identify it so I could get one! Now I finally can't take it anymore. Please help me. Does anybody here know what this badge is?
