Thank you to everyone who everyone who replied with suggestion ans
offers to help.

André Erasmus reconstructed the coordinates for me from the boundaries
of the current farm 270/1 and the 1998 consolidation diagram. He had
to convert more than one local coordinate system to one of the current
coordinate systems.

This list is a wonderful resource.

Thanks agian
