This instrument is marked “"KEUFFEL & ESSER CO NEW YORK." The raise rim around the face is graduated to degrees. A variation arc at the north end of the face extends 45 degrees either way, and reads by double vernier to 6 minutes. There are two level vials on the face, one at east and one at north. With polished mahogany case (here missing), this compass cost $18. K&E advertised compasses of this sort from the early 1900s through the 1940s. The company donated this example to the Smithsonian in 1972.
