Compound monocular microscope of the sort designed in the 1720s by the English optician, Edmund Culpeper. The body is brass, as are the three S-shaped legs. The base is wood, as is the triangular case. A drawer in the base holds extra parts. There is a rack-and-pinion focus. The sub-stage mirror and mount are missing. The “Silberrad / Aldgate LONDON” inscription refers to Charles Silberrad, an optician in business during the period 1799-1834.
