This is a compound monocular with rack-and-pinion, trunnion, tri-leg base, and one Crouch objective. The stage, large, solid and circular, has a screw that moves it from side to side, and a “J. W. Queen & Co. / PHILADA / 1184” inscription. A printed paper tag in the wooden box reads “JAMES W. QUEEN & CO.” While this instrument was obviously sold by Queen, it may have been made by Bausch & Lomb. Indeed, it resembles the American Type (or Library) stand, model DD, that Bausch & Lomb described as “a good working, simple instrument” designed “to take the place of the unreliable cheap foreign microscopes.”
