This is a fine collectors piece in very good order with all parts original and working well. Unusually it is complete with its original carrying case and key. It is difficult to fix an exact date of manufacture. Charles Baker was at 244 High Holborn from 1855 to 1959 when they were taken over by Vickers. No serial number list exists although the last was in the region of 40,000. This microscope has serial number 20158 and since the majority of Baker models were built towards the end of the period a reasonable guess would be 1930 or so. Finished in black enamel the body work and chrome parts are in good condition. Circular rotating stage with chapter ring and a worm screw mechanical slide attachment. Coarse and fine focus and a draw tube. Separate coarse and fine focus and a focusing condenser with iris and filter carrier. Objectives x19 (0.25), x40 (0.73) and x100 (oil) (1.25). Eyepieces x10 and x5. Mirror illumination and there is some tarnish to the mirror surface on the concave side. Original case, objective pots and key.

Leitz Binocular Microscope

As a collectors item they do not come much more complete than this. A black and brass binocular microscope with a serial number of 270502 that places its date to very early in 1929. It is complete with its excellent very well made wooden case which is an ‘Aladdin’s Cave’ of accessories and all in their original velvet lined boxes that fit neatly into the case around the microscope. The original registration card is still present and in its place. The only negative about the case is that the key has been lost.

The microscope stand itself is finished in black enamel with brass controls and is in very good condition for its age with very little corrosion of the brass. Mirror and gimbal illumination with the mirrored surface in very good condition. A rack and pinion focusing condenser with iris diaphragm and lateral adjustment. Above this is a circular rotating stage that has a brass mechanical specimen driver in place. Triple position objective turret with standard RMS seatings that indexes well. Focus is by the head movement which is controlled by separate coarse and fine brass adjusters. The rack and pinion is in good condition and the angled binocular head has its interocular distance controlled by a central adjuster between the eyetubes. The left eyetube has dioptric control. The head slides out easily when released to enable it to be replaced by the alternatives.

The case has the usual slide out racks for the eyepieces which are all original and comprise x6, x10 and x12.5 pairs. There is also a ‘pencil case’ type box for auxiliary equipment such as forceps, coverslips etc (not present).

There are two further substantial cases, one above the microscope and the other to its left. The first of these contains the following:

Six objectives that are brass with chrome end caps:

x6

x14

x42

x45

x95

x105

All are complete in their brass cases with the Leitz logo.

A monocular head with draw tube, and a vertical binocular head with straight vertical brass eyetubes. The brass of the eyetubes does show some tarnishing probably caused buy skin contact during hand adjustment over the years. It has interocular and dioptric adjustment. Either of these heads will couple with the back of the turret assembly when slid down the dovetail.

The second case contains a plain circular stage top with slide clips that can replace the standard stage top if required. Whoever originally owned this microscope clearly appreciated and looked after it with care. Exceptional opportunity.
