A brass sight for a surveying device was found 3 ft. from the pivotal mount, and the two pieces may have came from the same instrument. The sight (height 6 in.) is slotted twice for rough and pinpoint aiming, and the larger slot (1.8 x 0.4in.) is bracketed by two holes that would have held a crosshair. A setscrew attaches the sight to an index that is broken at a threaded fastener hole. When intact, the index would have held a second sight with opposing slots.
Material: Brass. H: 6".
