A tube-like section, ending in a polished metal handle, protrudes horizontally from the base of the instrument and ends in a circular polished metal handle. This section is supported by an elevated section of the wooden base.
Two cylindrical vertical elements, one taller than the other, protrude vertically from the instrument. The taller section ends in an optical ocular element.
