e leitz wetzlar binoculars serial numbers

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.

I used to stop at this NY/NJ highlands border area store for plants, pasteries, coffee.right on Rt 17.
