The badge is in very good condition and is embossed on the back Birmingham, England. I personally think the hook for the pin is a replacement as there does appear to be something also embossed beneath it which I discovered should read Stratton. The St and ton are visible but the rat are covered with the clasp hook. Having spent hours researching this badge I finally found it on the Leon Morel Catalogue of Medallic Commemoratives of New Zealand. That gives it an R5 rating and there is only 11-25 of these badges produced. It measures 45.5x42.4mm I do not make fixed price offers.
