Product details: C. Lewert Clinometer | C. Lewert | Clinometer | | Material: Brass
Graduated in gon rather than in mils. Made of brass. Very hard to adjust correctly due to the single locating nut (tightening the nut moves the arm slightly). Later models have a small adjustment screw which is not present in this model. It is not dated but based on later versions that are dated it is probably between 1850 - 1880.
