Curious Drum Microscope, Circa 1900. In good working order.

Curious drum type microscope made in 1900, which is especially attractive because of its small size and delicate execution, making up what we could define as a pocket microscope. Made of brass, it is in good condition, both aesthetically as functionally, and is doubtless a completely original and charming piece. Its simple design is perfect for its function: fieldwork. Also, it makes of this microscope an especially attractive item. In the base of the microscope we find an opening which contains the balancing augment mirror which makes easy the viewing of the specimens. The mirror can be tilted thanks to the shaft that passes through it, with a circular handle in the external part to operate it. The eyepiece has two cylinders fixed to the base by means of a vertical arm, which support a fixed lens. Drum type microscopes were invented in 1738 by mathematic and precission-material designer Benjamin Martin. As simple as practical, this design was quicky popular and it was repeated during two centuries without remarkable changes. The drum microscopes were very appreciated by students, as they were quite cheap. Nowadays, this beautiful microscope is a real museum item, perfect to decorate any study, office or showcase with the most exceptional antiques. Microscope measurements: 165 cm width x 50 cm high.
