Impeccable Large Antique Otto Seibert Microscope. Circa 1925.

Amazing big-sized Otto Seibert microscope, an antique and strikingly well-preserved piece. Though this is quite an antique item (the microscope was made in Germany circa 1926), this instrument and its accessories have survived to our days in mint condition. The microscope looks as if it were new and does not show any signs of the trace of time or the use; the same can be said about its fine light-colored wooden storing case. Another relevant feature about this item is its big size and complex configuration: it mounts a 4-lens revolving nosepiece and a micrometrical stage with 3 axes (moving upwards, downwards and turning). This is the biggest, most professional and complete model ever made by Otto Seibert, with universal foot. As well as being in impeccable condition, the microscope and its accessories work perfectly. The black-lacquered cast-iron bearing structure shines like the first day, while the brass and silvery-metal component parts (the turret, the screws, the lenses, the eyepieces) look as if they had just left the factory. At the top of the microscope there is a metal plate with the engraved manufacturers name and serial number: Otto Seibert 2242. Under the stage we can see the original double-sided mirror (concave and plane), perfectly preserved. Last but not least, the storing case is a lovely light-colored wooden box with the original metal handle, lock and key in perfect working order. Any good collector of antique microscopes will be dazzled by the high quality and mint condition of this wonderful antique Otto Seibert microscope. Measurements: Width: 7 in / 18 cm.

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.
