A polarizing filter is mounted in a dial that may be rotated using a small protruding brass handle. Markings indicating the orientation of the filter are inscribed along the outside perimeter of the dial’s housing. A brass handle, protruding from the base of this element, is set in a brass stand. Its height of this handle may be adjusted by means of a set screw on the stand. The base of the stand rests on three legs and has been painted black.
