Nice badge, the Army Medical Services wear/wore some badges like this. I understand that there were a total of six such badges 2 for SEN and SEN (Mental) and 2 for SRN and SRN (Mental). The 6 included 2 pewter coloured which were for nurses and dental technicians. Perhaps a kind forum member could post images for all to see. My wife has a small collection but we can't lay our hands on them at this time. They may be in an album somewhere on the forum already.
Are they still in use?
Thank you.
