Watson Service Microscope Serial Numbers



Baker Monocular Fallout 4 vault 75 quest.

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. How much does 0 pay in roulette. 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.

Read the description of the Watson Van Heurck microscope in the 1923 catalog. Elsewhere on this website is another example of the Watson Van Heurck No.1, serial number 10884, with a more elaborate stage having centering adjustments, calibrated stage movements, and rack and pinion stage rotation. Basic optical microscopes can be very simple, although many complex designs aim to improve resolution and sample contrast. Often used in the classroom and at home unlike the electron microscope which is used for closer viewing. This is a service II MICROSCOPE serial number 104008. Optical Microscope by W. Watson & Sons London circa 1940. A vintage WATSON SERVICE microscope A very serviceable Watson 'Service' microscope.
