SOUTH AFRICA MEDICAL MILITARY NURSING SISTERS BADGE - rare variant

SOUTH AFRICA MILITARY NURSING SISTERS PRE & WW1---SILVER VARIANT/ NO MFG. MARK . The round badge measures approx. 30mm across and it is in excellent condition albeit the rear pin is missing.  I'm told by a South African collector that this earlier variant is rarely encountered.      I am willing to ship at buyer’s expense or offer local pick up --- I am also in Red Deer one day per week and can arrange to meet there, or enroute, for delivery.
