Brass mountings and cap are turned, with milled edges. Objective lens housing screws into brass mount. The lens housing has room for another lens, so maybe the unit was achromatic. Brass screw-on end cap. The two eyepiece lenses are in brass mount, in turn mounted on a short brass draw tube (length = 46 mm). Metal aperture disc inside the draw tube. A sliding dust shield inside the eye hole rotates on an arc. Draw tube has screw threads for end cap (missing). Maker's signature engraved along side of draw tube.
