Before we get back to Florida, I dug up some more detailed information
about this unusual car. Ryno Verster of South Africa (and from whom I bought
the car) has been digging around trying to come up with a history of the
cars. Since no factory information exists he's had to do library research
through old magazine articles and has spent time talking to everyone with a
knowledge of the cars he can corner. The following is from his notes to me.

The cars were built in South Africa for sale from September 1967 through
November 1968 as Mk 1 models and December 1968 through August 1969 as Mk 2
models. The Mk 2 models seemed to adapt more of the Mk 2 characteristics of
the English Mini; e.g., the combination turn signal, high beam control.

According to Ryno: "The Wolseley 1000 Mk 2 sedan appeared for the last
time in "Car's" price list [this is the South African "Car" magazine -- older
than the English one of the same name] in August 1969. In September 1969, CAR
had a ten page feature article and Road Tests of amongst others the Mini Mk3
just launched and on BMC becoming LEYKOR. It seems that one of the objectives
of LEYKOR was product rationalization and the production of the Wolseley 1000
was stopped as part of this process. This also coincided with the launching
of the Mini Mk3. [How that is product rationalization, I don't know! The Mk3
had the round nose with a Hornet/Elf boot!] The axing of the Wolseley 1000
came at the very same time as the end of production of the Cooper "S" in
South Africa."
