With the compass and 3 spirit levels this instrument is adjusted like a surveyor's transit to measure inclination, and the actual angles on graduated scales, which are inlaid in white metal in the brass frame of the instrument.The brass frame is supplied in an antique looking finish.
This is an example of a truly practical old theodolite.
