Great Antique Seibert Microscope. Germany 1920

Superb antique Seibert microscope, a big-sized device in excellent condition and with an imposing presence. This item was made in Germany in 1920 and has survived to our days in amazing condition. The microscope comes in its original solid wooden storing case, which also contains a complete set of 6 eyepieces and 5 lenses. It mounts a three-lens revolving nosepiece, double diaphragm, original double-sided mirror and micrometrical-adjustment sample stage with three movements: vertical, horizontal and rotary. The microscope is made of cast iron with a fine glossy black-enameled finish. The mobile component parts (sample plate, turret, lenses and focus screws) are made of silvery metal and brass. The black enamel and the metal surfaces look really good: they are even, shiny and with scarcely any signs of the trace of time. The micrometrical stage and the screws move fluidly and softly. At the back of the microscope we can see the brand name SEIBERT WETZLAR engraved in the black surface, together with the serial number 16728. The device, the eyepieces and the lenses can be stored in the original light-colored solid-mahogany wooden case, in really good condition and with delicate artisanal dovetail joints at the corners. The case preserves the original lock-and-key set in working order. For its imposing look and perfect working order, this big-sized Antique Seibert microscope is an exclusive piece worthy of the best museum of science and technology. Measurements: Width: 7 in / 18 cm. Height: 15,75 in / 40 cm.Seibert Microscopes - History In the 1850s, Wihelm and Heinrich Seibert were working in the famous Carl Kellers optical company in Wetlzar. Enrst Gundlach was working there too, and in 1859 he left the company to start his own workshop, taking the Seibert brothers with him. He had poor business skills and soon the business went bankrupt; Gundlach moved to England in 1860 and came back to Germany in 1865. He started another microscope company and again the Seiberts went with him, but in 1872 the business was again in financial trouble. The Seibert brothers, together with Georg Krafft, bought the company. Gundlach had to agree not to found another business in Germany so he moved to the USA. Meanwhile, the Seiberts and Krafft returned to Wetzlar; the company was known as Seiberts & Krafft till 1884, and as W. & H. Seibert until 1925. After the death of Otto Seibert, Leitz Wetzlar took over the business.
