Antique Microscope 

by E.Hartnack & Co, Paris & Potsdam

 

Good example of a high quality microscope complete with three objective lenses and two eyepieces dating from the late 19th Century. The microscope parts are made of lacquered brass and it sits on a weighted horseshoe shaped base. The eyepiece tube is manually adjusted to provide the coarse focus and there is an additional fine focus wheel on the back. It has a square stage with two slide clips. Below the staging is a mirror to focus the light and a condenser lens. The tube is marked with the maker's name "E.Hartnack & Co, Paris & Potsdam".

 

There are three brass objective lenses all contained within their original fitted case and they come with 3 different pinhole end caps. There are also two brass eyepiece lenses.

 

The microscope appears to be in good working order and I have set it up and tested it with a few old slides. The microscope was easy to focus with both the main focus and the fine focus, and produced a clear and crisp image. I'm sure the lenses would 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. 

 

The microscope comes in it's original fitted mahogany box with sections for the lenses and an additional storage compartment. The box is stamped with the serial number "15679" which is also present in the lenses box. The box measures 11" high by 6" wide and 4" deep.

 

Overall it is in good condition but it has been used and will have normal signs of wear. The brass has been lightly cleaned and polished and it displays very nicely. There are some areas of tarnish and wear to the lacquer and some surface scratches but it is in good original condition and displays well. 

 

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