Gray Watson Barnet, Greenough-Style Stereomicroscope with Triple Turret This gray Watson has a triple turret, with three pairs of removable and replaceable objectives: 2.5x, 5.0x, and 10x. Two 10x matched Watson eyepieces, providing total magnifications of 25x, 50x, and 100x. It is supplied, as are all Greenough stereomicroscopes, with dual porro prisms. This Greenough microscope is named after its American inventor Horatio Saltonstall Greenough. The microscope, with its three objectives attached, weighs approximately 8 pounds 13.2 ounces. It is approximately 12-3/4 inches tall in working position. Its base at widest point is approximately 5-1/2 inches. It has attached illuminator for incident light, that can be easily removed (see photographs), albeit it does not include a transformer, and it has an adjustable substage mirror for transmitted light. The picture through the microscope shows detail of Abraham Lincoln’s eye on the front of a US $5 bill. The bill is not included in this sale. ______________________________ The London Manufacurer: Watson Barnet (Watson Barnet is now a subsidiary of Pye Instruments Group, which is majority owned by Philips) William Watson founded his company in c. 1837 at City Road, Clerkenwell, London. However, according to Bracegirdle (Bracegirdle, 1996), the first Watson microscope was not made until 1876, at which time the company was known as W. Watson & Son, and located at 313 High Holborn, London. The name was later changed to W. Watson and Sons, after a second son became part of the company. The company was still located at the 313 High Holborn address. William Watson died in 1881 and the last Watson microscope, with just the Watson name, was made c. 1970. The company initially gained renown with their non-stereomicroscopes, the well-made Van Heurck models, with two rack and pinion mechanisms allowing English or Continental length microscope tubes to be used. These instruments were based on the designs, and named for, the famed Belgian microscopist Henri Van Heurck. -- © RJK 2014 Authorized __________ No need for concern about stock picture matching the item for sale.
