Not many "Gallantry" Medals appear to have been awarded to the Rhodesian Prison Service.

We refer you to David Saffery's Book......Page 51.
If you got this Decoration you ended up with a R.P.M. after your Name.
"Quartermaster's Comment":-  On Page 29 he refers to a Prison Cross for Gallantry......but notes that it would appear that NONE were gazetted.
