Here are the SAA A300 fleet names:
Airbus A300B2K-3C (built 1976/7)
ZS-SDC Waterbok ("The Love Plane") // scr 09/2000
Airbus A300B4-203 (built 1981/2)
Airbus A300C4-203 (built 1982)
ZS-SDG Kudu (cvtd to freighter early-90s)
Airbus A300B4-203 (built 1982/3, ex-SIA)
ZS-SDH Bosbok (bought 1985)
ZS-SDI Steenbok (bought 1987, sold 1991)
The 3 newer pax B4s will probably be converted to freighters, but the other 3 remaining older pax aircraft, being B2s, are all likely to suffer the same fate as ZS-SDC.
If I remember correctly, the eight A300s were to be split between Boeing and GE as part of the trade-in deal on the new B737-800s.
Here's a photo of ZS-SDC taken by Propfreak at Cape Town Int'l (FACT) in February this year:
