Introduced in 1929, this model was quite a departure from the typical microscope design. The maker's description (courtesy Manuel del Cerro, microscopy-uk.org.uk): “DDE – A New Research and Photographic Microscope. The word “new” is so often used to describe a revamped apparatus that one hesitates to use it but in the case of this Research Microscope, the word “new” can certainly be used in the fullest sense of the word. This instrument is a radical departure from any existing type of microscope. When we took under consideration the design of a new Research Microscope, we adopted the suggestion of Dr. Lester W. Sharp of Cornell University and of his associate Dr. L. F. Randolph of the U. S. Department of Agriculture and Cornell University of placing the arm at the front of the instrument, so as to give free access to the object, stage, objectives, sub-stage and mirror and thus offer greater convenience and comfort to the user. With the further aim of providing extreme rigidity we have eliminated the usual inclination joint for arm and pillars, which are made in one piece. The stage is thus always horizontal except when the instrument is used photomicrographically, when the entire instrument is placed in horizontal position resting upon three bosses provided on the two arms and base, thus leaving each part intact and in the vertical stage.”[Italics in the original] For more information regarding the history of this microscope, please go to: http://www.microscopy-uk.org.uk/mag/artmar07/mdc-dde.html The microscope for sale is in very good condition and includes FIVE B & L objectives (10X, 43X phase contrast, 45X apochromat, 90X and 97X oil immersion), all other optics, adjustments, stage, etc). It dates from sometime between 1929 and 1946 (based on serial number, the '30s?). It DOES NOT include a box and although I'm pretty sure it is working order, it will be sold AS IS with NO RETURNS.
