Description
This is a transition form of Jackson Model no.6 Scientist's Model microscope produced by Watson & Sons.

The microscope is based on the Jackson-Lister pattern, with the characteristic "crescent moon" shaped limb. This pattern was popular in the late 19th century and was introduced in the early production of Watson & Sons firm (after 1882). The micrometric control thumbwheel is on the limb. This type of micrometric fine adjustment was also introduced in the Watson catalogue of 1884.

The serial number '2264' on the foot dates it to 1888-1889 (Ref.: B. Bracegirdle, Notes on Modern Microscope Manufactures, p. 80).
