I don't know if you already have but it's worth searching the forum for "stickpin". Jo Rivett has posted some very useful information on them (example). Does yours have any markings on the reverse? What size is the badge? Normal or mini? Based on those pics it almost looks to be in relic condition?
Hi - I do'nt like the front of the badge, i think that it is crude made. BUT the pics is not good enough to be sure, if you want further comments please take real close up pics.
