A fine and unusual large format microscopists bullseye condenser with black enameled base labelled “Fiddian’s Microscope Illuminator”. Standing 12″ tall with a 6″ arm terminating in a 2 1/2″ plano-convex lens, this accessory has seen little use. Friction adjustment of the height of the condenser, extension by brass rod and knurled tightening collar, brass bound lens ( perfect) and a black enamel 3″ hollow brass base. The lens itself can pivot 360 degrees on a brass pin and the whole assembly can pivot 360 degrees on the brass upright. The base is unweighted but very stable and well balanced. c. 1900. Have never seen another example.
