DeZeng ophthalmoscope with battery handle is in very good condition.
This DeZeng opthalmoscope from 1922 is in excellent condition. It still contains the original dry cell battery by Ever Ready of England.
The battery is dead, no doubt; but, it never leaked as modern batteries do.
It comes with its original case and the original dry cell battery.
DeZeng eventually became American Optical and later Reichart.
