Nice uniform. I have been trying (for some time) to find out about the various "Home Guard equivalient" organisations in South Africa during the Second World War. Not much available on the subject it seems. Great to find a picture of a uniform.
There were the "Civic Guard" and "Civil Protection Services", each with their own badges but seemingly similar duties (?), which seemed to have been controlled by the Police. There was also a police reserve.
Then there were the Essential Services Protection Corps which guarded key points,the Reserve Brigade (mainly guarded airfields), the Coastal Defence Corps (coast gunners), National Volunteer Brigade and National Reserve Volunteers (essentially the home guard) - part-timers who fell under the Army for control.
