Fedorov table for miscroscope

This is special device for a polarisation microscope allowing to position a crystal in space. It allows to determine isotropy, uniaxiality or diaxiality, optical sign, direction of optical axes and other optical properties of a crystal.

Excellent condition. Seems to be a complete outfit, though I'm not sure since I'm not a microscopist.
