Description
A brass micrometre kept within a dark wooden box. The micrometre is three individual pieces that fit together to form one complete measuring instrument. There is one long tube with a flat slide plate at the end, one smaller tube with a circular clamp and screw to tighten at the side end, and one circular hinged mirror. The box the micrometre is kept within is hinged and has a key hole on its front face. Within the box are raised sections of wood, lined with green velvet. These sections have been shaped to fit and securely hole the contours of the micrometre in place. The lid of the box does not close fully, is held up by a piece within the box.
