Antique Watson & Sons Microscope

'Edinburgh' Model

Circa 1900

Fine example of a high quality antique microscope complete with three eyepiece lenses and three objective lenses. The microscope parts are made of brass on a black tripod base. The whole microscope tilts, the eyepiece tube is extendable and focuses using a rack and pinion system with two brass knobs either side of the tube. It also has a fine focus knob on a round dial at the back of the microscope. It has a triple revolving nosepiece and a square shaped stage with a mechanical slide holder with two slide clips. Below the stage is a large adjustable mirror for focusing the light source towards the microscope. The substage apparatus is complex and has, among other pieces, a condenser, an adjustable aperture ring and a filter holder ring. The whole sub-stage moves up and down by a rack and pinion system and a brass knob below the stage. 

The microscope is stamped on the back leg with the makers name "W.Watson & Sons Ltd. 331 High Holborn St. London" and serial number "23410". The microscope comes with three eyepiece lenses, two marked W for Watson and x6 and x8. There are three objective lenses, the first a E.Leitz number 7, the second a W.Watson 1/6in and the third an Otto Seibert Wetzlar 2/3". The microscope comes in a fitted wooden box with sections to hold the lenses. The box is stamped on the door with a different number to the one on the microscope but it is definitely the right box so possible that a few of the same microscopes were used in a lab or office and they've ended up in different boxes. 

The microscope measures approximately 13" tall and extends up to 16" tall. It appears to be in good working order and I have set it up and tested it with a few old slides and attached some shots through the eyepiece. The pictures are clear and crisp and the microscope is easy to focus with both the main and fine focus. It also benefits from having cross lines on the field of vision. I'm sure the lenses would probably benefit from a light clean and it is being sold as a collectable item rather than an accurate scientific instrument.

Overall the microscope is in good condition for its age. It has been used and will have normal signs of wear. There are some areas of tarnishing and wear on the brass lacquer where it has been handled and some general knocks and light scratches around the base which have chipped some black paint but nothing detrimental. It has been cleaned and the brass lightly polished and it displays very nicely. All parts move smoothly as they should. The box is strong and sturdy and has a nice aged patina although it does not come with a key.

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