Description
This is a compound monocular with rack and pinion for coarse focus, and mechanism on the limb for fine focus, square brass stage, trunion, and V-shaped iron base. The lenses and sub-stage mirror are lost. This resembles the Universal and Household microscopes available from such American dealers as McAllister and Queen in the second half of the nineteenth century.

"This is almost certainly a J. and W. Grunow microscope made in either New Haven or New York. The signature and serial number can be found on the right side of the main tube about an inch down from the top. The signature is rather small and delicate. Compare to Billings Collection catalogue Fig. 111, Note the distinctive rear fine focus and side plates guiding the main tube."
