Antique Brass Microscope

Circa 1850

Fine example of a mid 19th Century brass microscope in a fitted wooden case, complete with an eyepiece lens and objective lens. The microscope is made of lacquered brass. It tilts, has a rack and pinion main focus and additional fine focus on the back of the main tube. It has a square brass stage with a manually adjustable slide rest. Below the stage is a large adjustable mirror and a revolving plate for narrowing the field of light. 

The microscope measures approximately 11" tall when not extended. It is unsigned with no indication of a maker but the craftsmanship is superb. The brass objective lens is excellent quality but also unsigned and the microscope comes with a single eyepiece lens. 

The microscope comes in its original fitted wooden case with a small pull out drawer for storing slides. The box is good quality with an inset brass military style carrying handle and a nice aged patina and it comes with its original working key. There are some general signs of age and light marks on the box but overall it displays very nicely. It measures approximately 12" high X 6 1/2" wide X 4 1/2" deep. 

The microscope appears to be in good working order and I have set it up and tested it with a few old slides (see photo). I'm sure the lenses would probably benefit from a clean but they produce a clear and bright image all the same and the microscope was easy to focus. Although in working order it is really being sold as a decorative / collectors item rather than an accurate scientific instrument.

The microscope is in good condition for its age and the brass has been lightly cleaned and polished. It has been used and will have normal signs of wear so please don't expect it to be like new. There are areas of tarnishing where it has been handled are some small knocks and light scratches but nothing detrimental. There is a small chip on the outside of the eyepiece lens (see photo) but it doesn't affect the vision. 

The best description comes from the photos so please look at them all carefully and if you have any questions at all please ask.
