Using a mounted diatom slide prepared for me by Walter Franchini.the #'s 3,4, and 6 objectives seem like : 10X, 20 X, 40X.I did not calibrate this estimate. The objectives are brass with dull (lost their shine over time?) silver end assemblies. Their are a pair of oculars marked:"6X", and a pair marked:" 4 B ", E.Leitz Wetzlar is etched on all oculars, all objectives.
All with their original black metal screw cap 'pots'. Na 1.3 objective, then three objectives marked: "6", "4", "3". No markings on it's condenser, the iris and filter tray work smooth for this condenser, A wooder rack holds: Object marker, 1/12 oil-immer. It has both a monoc head, and binoc head, both with same serial number.the binoc head 'breaks your neck' if you don't tilt the stands axis.
Of course it's wooden case was bashed horribly in shipment.sigh.
I used a professional microscope dealer/service company in Hicksville,L.I, NY to clean it's already good optics and mechanism. One year in the fall.there it was in it's original box with no pamphlet.surrounded by Fall season, Halloween decorative gifts. The serial number indicates a date of manufacture between 19.I used to stop at this NY/NJ highlands border area store for plants, pasteries, coffee.right on Rt 17. Be careful, the lens iis not attached may be removed and lost. There is an opaque glass lens beneath the condensor which may be rotated in and out of position beneath the condensor. The binocular eyepieces are both present and adjustable.
The device has a movable stage and a revolving nosepiece with room for four objectives. The exceptions are knobs and the slide holder which are stainless. Virtually the entire microscope is painted black.
