I've obtained this level in 1995. The instrument is of Swiss origin. It's a very basic level with no compensator or tilt adjustment.
The instrument was not complete when I got it and I added a remake of the plate level mirror myself. I made it of brass and left it unpainted as to show that it is not original. At the base there is a 360º scale for simple angle measurements.
