The theodolite was made in 1936. The instrument features a modern theodolite design patented by Heinrich Wild in 1921 with the Zeiss Th1 model and later perfected with the Wild T2 model. The cylindrical axis clamped to the detachable base, the ball bearings, the glass circles, the reading by means of a single microscope and the centric alidade toric level are just some of the revolutionary technological improvements. Regarding its precision, the instrument is a second-order instrument, and the readings on the circles are determined to 2''. The coincidence vertical circle level, the screw microscope, and centring with a plain plummet are some of the shortcomings that have been overcome by further technological developments.

The instrument was used extensively for teaching work until the end of the 1970s, especially for the measurement of polygonal and connecting nets. In 2016, it was newly lacquered and the screws were cleaned. Unfortunately, the color of the instrument is perceptibly different from the original color.
