Merrill Dry Card Azimuth Compass

Description
This compass may have been used during the Civil War. It has a bright green card, a pair of vertical sights that can be aligned with astronomical (or true) north, and a mechanism that lifts the compass card off the pin. The inscription reads "U.S. NAVY / 21 ROBERT MERRILL / NEW YORK. XXI XXII." Robert Merrill (fl. 1838-1864) was the leading nautical instrument maker in the U.S. during the middle decades of the nineteenth century. The firm became Robert Merrill & Sons in 1865, and continued under similar names until 1923.
