You are bidding on a U.S.E.D. (United States Engineer Department) Creagh Osborne Marching Compass Mark VII Mod. E manufactured by Sperry Gyroscope Co. of Brooklyn N.Y. The back of this compass is marked "U.S.E.D. CREAGH-OSBORNE MARCHING COMPASS MARK VII MOD. E SPERRY GYROSCOPE CO. BROOKLYN, N.Y."

About the manufacturer:
Frank Osborne Creagh-Osborne (1867-1943), Superintendent of Compasses in the Royal Navy, introduced this type of instrument in 1917. The Sperry Gyroscope Company was established by Elmer Ambrose Sperry in 1910 and became the Sperry Corporation in 1933.

Condition (see pictures):
This compass is in poor condition but a nice piece of history.  The GOOD: The magnetic disc still spins and appears to find north and the view finder glass is good and does turn in and out.  The Bad: The glass top is cracked and the fluid has leaked out.  1 of the 6 screws that holds the top flange and glass in place is missing and the green paint is worn off of the brass in several areas.  
Look at the pictures and judge for yourself, this compass is very nice for its age. (over 100 years old)
