Keuffel & Esser Surveying Compass with Folding Sights

This is one of the earliest instruments made in the factory that Keuffel & Esser built in Hoboken, N.J., in 1880. The face is marked "KEUFFEL & ESSER / NEW YORK / 183." The circumference of the face is graduated to 1 degree, and there are two bubble vials, one at north and one at east. The variation plate is on the outside of compass box. This originally had a ball joint and socket for mounting on a jacob staff. New, it cost $20.
