John Browning Compound Microscope
The binocular microscope is marked "John Browning London. 280" on the stage. The compound microscope is made from brass and stands on a splayed Y-shaped foot with a decorative varnish. The lower limb ends in an inclination joint which allows for angling for observation. The microscope also consists of a sub-stage plano-concave mirror which sits in a gimbal and an arm extension which allows for adjustment. The square stage also has a decorative pattern which matches the foot. The stage has an attachment to hold the slides in place as well as two removable stage clips to hold slides in place. The slide can be adjusted via the X and Y axis by the two thumbscrews on the side of the stage. The instrument also has a sub-stage iris diaphragm with three apertures which can be adjusted by swiveling the disc. Coarse focusing is achieved by a rack and pinion mechanism controlled by a large thumbscrew parallel to the stage. Fine focusing is controlled by the by a smaller thumbscrew at the end of the body-tube.
