The level was made in 1946. Rough levelling is made possible by a circular level. Through an additional microscope, we observe a coincidence levelling toric level – the prism system maps the edges of the bubble into a single image. The toric level culminates when the edges are aligned. It is culminated by means of the tilting screw. The instrument has a telescope with internal focussing and a 35 mm objective with 31x magnification. The crosshairs are Reichenbach crosshairs.
In 2016, the instrument was partially lacquered and the screws cleaned. The mirror of the coincidence toric level has been renewed.
