An English brass binocular microscope signed “John Browning London” and numbered “404”. We can date the microscope, circa 1880.
The microscope is a classic Browning binocular example with Wenham binocular double body tube and pirsme (the prism has small external cracks and very little lacks but it is still working), a rack and pinion focus and fine adjustment.
The stage has two rack and pinion, for horizontal and vertical movements. The binocular space between the two eyes can be adjusted by sliding.
The microscope preserved also is sub-stage condenser, a substage rotative diaphragm and his mounted bulleye.
The microscope was formerly entirely polished and his preserved in a nice case also formerly refurbished.
Size of the case : 40x17x21 cm ; height of the microscope : 40 to 43 cm.
