notes: label: Description
content: This instrument belonged to the University of Missouri–Columbia. It dates from the late 19th century, but represents a form that was widely used in the 18th century. It has a pair of sight vanes (one missing) attached to the circle, and another pair on the alidade. The circle is graduated to 30 minutes, and read by vernier to single minutes. The signature reads "Blattner & Adam St. Louis" and "No.5698." Henry Blattner and Frank Adam were brothers–in–law who worked together from 1872 to 1891.
