Two mill-headed knobs rack a bar up from within the limb and an arm at the top of this bar holds the binocular body. The circular stage has a rectangular bracket to hold specimens and a pivoting arm, to hold the bull's-eye lens, is attached to its underside. A cylindrical post extends below the stage that holds the Plano-concave mirror in a horseshoe mount. The microscope can be folded for packing into the mahogany case. The case also holds four eyepieces, four eyecups, a sub stage condenser mounting with rack and pinion focusing, two Nicol prisms, an assembly of sub stage apertures, a square graticule and a bull's-eye lens on an articulated arm. A pillar for a lens on a stand is also present.
