Hi Lee
when south africa went over to the yellow and black plates it wasnt based on anything except a system for numbering cars
Only the Transvaal Province used this plates and a rough (very rough) estimation of date of registration can be made based on the first digit
As all cars were required to go over to the new system it meant that cars and first digit did not match at all
In 1982 I rebuilt my first vehicle an old 50cc motorbike and the registration was HWS 685T
IN 1988 I bought my first new car in September and it was registered as MWY 234 T
My 87 Passat wore an LNM 999 T
So my guess is that your number was registered in the transvaal around 1990
Prior to this system cars were registered to the province and town
with T the suffix for transvaal
O the suffix for Freestate
N for Natal
C for the cape province
My home town of orkney was thus TOY and the OY signified Orkney Still the cooles of the lot
Search wikipedia for a list of all the towns
