A post below the stage holds the plano-concave mirror on a sliding sleeve. The accessories comprise a bull's eye lens on a copper alloy pin, stage forceps, a camera lucida, an objective in a can three objectives in cans, two lieberkuhns with caps, two dark wells on stalks, live box, erector lens, cone condenser, a copper alloy tray, a substage plate, a side reflector, and a specimen compressor, stage pin and stage fitting.
