Bate Tilting Level

This somewhat unusual instrument has a micrometer screw at one end, to be used for fine adjustment, and its telescope has the same diameter from one end to the other. The “Bate London” signature refers to Robert Brettell Bate, an instrument maker who was active during the first half of the 19th century.
