These look very like a thing we have in collection described as a
textile tester. I think the material was held taut, the ceramic thing
pushed from one side and a largish ball bearing from the other.

<<IMAG1534.jpg>> Dear colleagues
Does anyone happen to know what these objects are? See attached
picture.
I think that perhaps they are insulators (but for what?)
If anyone has more exact information I would be glad to hear your
insights.
Many thanks
