Here is a Victorian brass monocular microscope made by Charles Baker of London circa 1880.  It comes in its mahogany case with some accessories.

It is being sold as a display piece only, and is untested.

It measures 30 cm tall when fully extended, weighs 1.95 Kg, there is some tarnish to the brass, and the case has a fair bit of wear.  

Please check photos for a closer look.
