Hiya Michael,
I don't know if all police badges are the same apart from the lettering, but I have the North Wales Police Badge in Vistool,.. which I think you have, maybe with a bit of jiggery pokery you could alter it. I've had a look and the basic outline seems the same apart from the wording and the swords in the middle. I could send you the one I have and you could explode it and have a fiddle about with it
