Antique Microscope by Armstrong & Bro, Manchester

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 side of the tube. It has a square brass stage with a manually adjustable slide rest. Below the stage is a large adjustable mirror.

The microscope is signed with the makers name; "Armstrong & Bro. 88 Deansgate. Manchester" 

The brass objective lens is unmarked and comes in a matching brass lens holder. The microscope also comes with a good quality eyepiece lens. 

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.

It comes in its original fitted case with sections to hold the lenses and eyepiece tube. There is also a pull out tray for holding slides and the microscope itself sits screwed onto a wooden board which also slides out of the box to make removing the microscope easier. The box is good quality with a brass carrying handle and a nice aged patina. There are some general signs of age and light marks on the box and some historic damage on the door which has been filled and repaired at some time but overall it displays very nicely.

The microscope measures approximately 13" tall when not extended. The box is a compact 10" high X 7" wide X 6" deep. 

The microscope is in good condition for its age and he brass has been cleaned and polished to a high standard. It has been well used and will have normal signs of wear so please don't expect it to be like new. There are some small knocks and light scratches on the base and a minor dink in the tube some. The lenses have small specks of dirt on and although in working order it is really being sold as a decorative / collectors item rather than an accurate scientific instrument.

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