Watson Edinburgh turn of the century brass microscope

The distinctive profile of the Edinburgh model Watson microscope was first introduced in 1887. It measures 13" high when fully closed, and is marked, "W. WATSON & SONS, 313 High Holborn, London" on the base. The serial number of 5594 would date it circa 1900. Its fully integrated mechanical stage works smoothly in all directions. There is a sub-stage Abbe condenser with lateral centering adjustments, and filter holder and variable diaphragm. Coarse focus is rack and pinion, and fine focus is with a micrometer indicator knob on top of the column. The plano-concave mirror is in excellent condition. The microscope has two objectives: a 1" Watson Panachromatic with matching brass canister, and a second, unmarked, at about " focal length. Both are sharp and clear. Two eyepieces, marked "B", and "C" accompany the set. The finish is lacquered and black-painted brass. The varnish coverage is about 90% with wear spotting over the barrel. The varnish has a deep copper color. The coverage of black is nearly complete with brassing on the edges of the stand. The microscope comes with a dove-tailed mahogany case with a leather handle. The case is in very good. This is a distinctive style of microscope that always makes a very impressive display.
