This is one of the most amazing microscopes I have ever seen. This Carl Zeiss Jena IVa Continental Model Microscope is in such wonderful condition. Everything works! Serial# 36513 makes it to be around 1901. Made in Germany. The IVa Continental first was made in 1897. This particular one was owned by a Dr. William G. Rush. There is a torn business card of his in the wood case. Several of his own home made prepared microscope slides dated 1915 are in the wood box that fits into the case. There are also several blank slides. The finish on the microscope is amazing! There is very little tarnish. Even the mirror surfaces have good aluminization. The microscope comes with four eyepieces and three objectives on the revolving nosepiece. The diaphragm under the stage works very well. All coarse and fine focusers work very smoothly. The diaphragm and mirror move up and down by an adjustment knob. The diaphragm even slides horizontally by turning an adjustment knob. A few extra small glass lenses are inside of the three brass canisters. This microscope is museum quality!!! The wood case is a wonderful furniture quality hardwood. The key is inside the case. Also in the case is a booklet by Spencer Lens Co. entitled "How to Use and Care for the Microscope". You will be extremely please with this microscope. It is in working order, plus will make a great display piece for the science classroom, office, of home.
