Antique Brass Microscope
By Newton & Co, London
Fine example of a high quality early 19th Century microscope in a fitted wooden case, complete with a range of lenses.
The microscope is made entirely of lacquered brass. The microscope focuses using a rack and pinion system with two brass knobs either side of the tube. It also has a fine focus knob with a round dial at the back of the microscope.
It has a square stage with an adjustable slide holder and two metal slide clips. Below the stage is a large adjustable mirror for focusing the light source towards the microscope. There is also a revolving ring to control how much light gets through.
The microscope comes with its original brass eyepiece lens and original triple stacking objective lens with matching brass lens case. The microscope itself is unmarked but the lens case is engraved "CAS Microscope. 1 1/2". Newton & Co. Fleet St. London".
The microscope dates from the first half of the 19th Century and so uses a very early thread for the lenses. Therefore in addition to the original lenses there is a thread converter and an additional brass objective lens. This converter allows later lenses to be fitted. A converter has also been made to sit in the top of the eyepiece tube which allows the smaller later eyepieces to be used and the microscope does come with one additional eyepiece.
The microscope comes in its original fitted wooden case with sections for the eyepiece lenses and a drawer for holding accessories or slides. It is a good quality box with a lovely brass carrying handle and its original working key. There is no major damage and it has a lovely patina, however there has been an old glue repair to the panels of wood on the door. It is also worth noting there looks like there would have been another wooden rack for holding lenses which is now missing from the interior.
The microscope measures approximately 15" tall. The box is 16" high X 7"deep X 6" wide.
The microscope appears to be in good working order and I have set it up and tested it with a few old slides - see photos. The pictures are clear and crisp and the microscope is easy to focus with both the main and fine focus. I'm sure the lenses would probably benefit from a light clean and although in working order it is really being sold as a decorative collectors item rather than an accurate scientific instrument.
It is in very good condition for its age. It has been used and has normal signs of wear and age. The brass has tarnished in places and there are some small knocks and scratches around the base but nothing major. There are a few small dents around the rim of the objective lens but it hasn't damaged he glass and it still works well. The microscope has been cleaned and the brass lightly polished and it displays very nicely.
The best description comes from the photos so please look at them all carefully and if you have any questions at all please ask.
