Zimbabwe sets from soapstone are less common than the kisii stone (which is a soft kind of soapstone) ones from Kenya. Striking at these sets from Zimbabwe is that the Knight is also a human figure.
I do not know much of the first 2 sets. Actually they let me think of the sets from Malawi. The unpainted 1st set has very subtle colour differences which are hard to see, even at the picture.
Zimbabwe. Of the third set could seller not tell me age or origin, but in Munger is a similar set from Zimbabwe.
