Antique Microscope-Pen, 1920s.

This curious item is an antique pocket pencil microscope, a rare surveying and study instrument made in England in the 1920s. The microscope comes in its original protecting box, with an instruction leaflet that shows off a nice engraving depicting the instrument. It is in good condition and working order: the lens is slightly dusty but allows a great visualization of the samples. The magnification provided by the microscope is really surprising; this detail turns it into a functional and charming item. As its name indicates, the microscope is shaped as a pencil and is of the same size. It is quite easy to use: in order to watch the samples, the user must place the cut awya end over them. At the other end, the black ended , the user has to put his or her eye over this end to watch the sample. In order to see a clear sharp image through the eyepiece, the user must move the roughened ring or knob at the lower end up and down. The pocket pencil microscope is made of silvery metal, in good condition and with scarcely any traces of rust or wear. The lower end with the lens mounts a black rubber knob that protects it and makes it possible to hold the microscope steady. The storing case is a dark blue cardboard box, quite well preserved too. The leaflet that comes with the microscope bears a printed description of its applications (to be used by engineers, lithographers, textile workers, botanists, geologists, nature students or motor mechanics) and a detailed explanation of how to use it. As special as interesting, this antique pocket pencil microscope will delight any lover of science-related antiques. Measurements: Length: 5.1 in / 13 cm.
