Description

A good c.1800 acorn style flea glass microscope converted by a naturalist to act as a live box viewer and microscope. By drilling holes through the entire assembly and with the addition of an eyepiece/ocular lens, this pocket microscope now acts as a simple/compound microscope and live box viewer. All  parts are present and could be restored to original with the addition of a spike and simple lens. All components show roped machining of the brass and the innovation to a live box pocket viewer is unique. Perfect optics and 40-50 x magnification possible, thanks to the addition of the eyepiece lens. Removable live box insert in the base allows for capture and viewing of flora and fauna specimens. Elegant and functional. Can be viewed in both directions for variable magnification. A little engineering marvel of the day.

As a simple flea microscope these popular pocket models were relatively useless as the optics were fixed and of low quality and magnification. This modification makes the instrument more useful yet retains it’s pleasing form.
