It's a long established South African company that specialised in cargo, medevac and charters for the SADF during the guerilla war, and to the Antarctic for the Navy. They have a few Hercs.
Indeed! Started off with ZS-GSK L100-20 in the 70's. A lovely aircraft to fly.
Ended up with 16 or 17 L100-30's, I cannot remember the exact figure; I brought ZS-JIZ across from Dobbins Air Force Base.
One of the best companies I had the privilege to work for.
