Rhodesian Army Medical Corps - Keays cap & collars
 

For the size of the Rhodesian Army Medical Corps, it has had a number of different badges over the years. I have been looking through Radfords book, Service before Self and I am certain that I'll never find all the badges that he mentions.
It seems that in 1940 the jeweller, Keays made an unofficial cap badge which is found in brass, cast brass and sheet silver. The cap badges were marked "Keays JL " . The one I have is cast brass which has been gilded and is slightly "taller "than the official badge.
