Thanks to all who have kindly replied, and for your willingness to share images. In my biography I have tried to illustrate the full official insignia of each service corps, complete with motto, which is not too difficult when my chap is with the RFC and later RAF, although I am still awaiting a reply from the College of Arms on a particular point ... but the NMR being a volunteer body makes me wonder where to find the full official regimental insignia for any given period, because who was in charge of such things? Which is why I thought of you people who are experts on badges. I'll PM Alex since I'll be able to go into more detail that way, but I hope everyone will forgive me for being confused as to why a variety of designs (apparently at the same/similar times) were used on badges for different items of clothing. It's turned into a fascinating discussion.
