The telescope is made of brass and consists of a 33 1/2" tube on 25" axis with a 1 3/4" aperture and a focal length of 32". Mounted on a brass stand of two rigidly connected A-frames, for use on a table. There are crossed hairs in focal plane, semi-circular scale of 9" radius attached to the bottom of the tube, and a suspended spirit level. Its construction is generally in accordance with earlier European convention. Unmarked. (Robert P. Multhauf, "Catalogue of Instruments and Models," 1961).

Pine case without embellishment. The dial is 10 5/8" diameter, probably of cold silvered brass. Unmarked. Heavy brass plates with a pillar at each of the four corners contain the deadbeat escapement and going train of two many-toothed wheels. The motion work is between the dial and front plate. A small gear on the #2 gear arbor drives a large gear carrying the minute hand. The hour hand is driven by the latter gear through a compound idler gear and pinion. The second hand is mounted on the escape wheel arbor. The pendulum vibrates seconds and is mercury compensated. It is in two pieces connected by a yoke, and suspended by two springs. A thermometer is mounted on the back of the case. (Robert P. Multhauf, "Catalogue of Instruments and Models," 1961).
