At the time this microscope was produced the McIntosh Battery and Optical Co. of Chicago manufactured several different microscope models. Among these were the New Clinical Microscopes No.'s 1 and 2, the Scientific Microscopes No.'s 1 and 2, and the Professional model. The latter had the unique ability of being detachable and used as a projection microscope (The earliest version of this type of microscope is present in this collection). The New Clinical model No. 2 differed from the No.1 only by having a rack and pinion coarse focusing mechanism in addition to the fine focusing mechanism. With optics, this microscope was priced at $37.00 in 1895. Some of these microscopes are described in the 1895 catalog of Stereopticons and Sciopticons.
