The objective screws into the lower thread and the nose of the body tube screws into the top. The eyepiece has a blackened eyecup and pushes into the upper cylinder of the body. The square stage has a large, recessed hole and a pinhole for accessories. A bracket, in the shape of a square U, is mounted on two pins on the stage to hold specimens.
