The eyepiece is then screwed into place at the top of the conical end of the body tube. The sawtooth arm is fixed below into a tripartite brass base of footing and is meant to be used in a vertical position only without the ability for the instrument to sit at an angle for the viewer. There is round stage, seen with two brass extensions which are attached to the focusing brass knob which currently sits at the top of the arm. The knob and the stage moves along the pillar by a rack-and-pinion mechanism using the saw teeth as individual gears. There is also a reflecting mirror with its iron pin which fits into the base of the arm and would reflect the source of light, often the sun itself or a flame at night.
