These were given to me many many years ago (in Aus) by an elderly guy and I cant recall him ever saying what they were. I haven't been able to find out what they are other than they appear to be some sort of military button and i am confused as to why there are buttons for two different monarchs in what appears to be an original set.
Anyone able to advise what they are and/or why there are buttons for 2 different monarchs.
