Vintage inclinometer and case is a great addition to any scientific collectables collection.

The instrument is of unknown origin but likely to be 1950 or 1960 and possibly (likely) manufactured in the USSR.

On top of the disc is a conversation table, the long word seems to mean 'proportionaltly'.

You look through the lens with the disc vertical and point up or down a hill, when you release the button the instrument records the angle of the slope.

The item is perfect for anyone interested in scientific collectables, especially those interested in optical items. The piece is a great conversation starter and would be a perfect addition to any collection.
