Here are a few that I have, but your best bet would to go to a web site that makes the patches, I'm sure you

We've had a hideous modern logo for a while now. I don't know anyone that likes it... Our all career neighbours seem to be having an equally hideous modern logo shoved onto them, their great old badge (picture in my photos if interested) is so much better! To me an FRS emblem is something that should be changed only with care - it's part of tradition that I'm all for keeping.
