The Model IIIE microscope with large mechanical stage, c. 1910
The case bears a plaque with the name of a previous
owner, Dr. David G. Yee. It was purchased in Bombay
around 1950 as a gift for Dr. Yee and therefore, he
is not the original owner. However, written in faded
ink on the bottom of the magnification chart is a
signature and the name of an institution: St Francis
College, Bombay (established in 1859).
Extract from the 1913 Zeiss catalog:
c) Stand III.
Stand III differs from Stand I in that it has not the wide tube of the latter. Hence projection lenses of very low power can either not at all be used with it or this can only be done by sacrificing the outer portion of the pencil of light transmitted by these lenses. When used for photo-micrographic projection or photo-micrography it can be so employed with microscope objectives only. In its adaptability for ocular observation it satisfies, on
the other hand, the most exacting requirements. In the place of the polished foot it is fitted with a horseshoe foot which is neatly coated with crystal lacquer.
The stand is so arranged that it may initially be acquired with an equipment comprising the indispensable components only and subsequently supplemented by the addition of other object stages or complements to the illuminating apparatus.
The stand is supplied with or without Revolving Nosepiece. as may be desired.
