Purchasing brass microscopes
made by Joseph Zentmayer during the last half of the 19th
century.
Joseph Zentmayer was a German immigrant who arrived in America in 1848 at age 24. He worked as an instrument maker with various firms in Germany and then in the Northeast USA until he went out on his own in Philadelphia in 1853. The first large microscope he constructed was the Grand American model, which was produced from 1858 up to 1876, when production of this model ceased and was replaced by the American Centennial model microscope. Zentmayer also produced the United States Army Hospital model microscope, which was originally designed in 1863 for use by the U.S.A. Medical Department during the Civil War.
Also buying all other kinds of
antique brass microscopes and accessories. Old microscope oil lamps,
prepared slides, and slide cabinets. Other types of antique scientific
instruments also wanted.
Here are some links to Zentmayer microscopes in my collection:
