Description
Frank Osborne Creagh-Osborne (1867-1943), Superintendent of Compasses in the Royal Navy, introduced this type of instrument in 1917. The bottom of this example is marked "U.S.E.D. CREAGH-OSBORNE MARCHING COMPASS MARK VII MOD. E SPERRY GYROSCOPE CO. BROOKLYN, N.Y." Here, “U.S.E.D.” stands for United States Engineer Department (aka Army Corps of Engineers). The Sperry Gyroscope Company was established by Elmer Ambrose Sperry in 1910 and became the Sperry Corporation in 1933.

HAVE ONE IF THESE IN MY HAND FOUND AMONG MY FATHER’S ITEMS. HOWEVER, CANNOT QUITE UNDERSTAND HOW IT WAS USED. CAN SEE THAT THERE IS A CERTAIN AMOUNT OF FLUID INSIDE. CANNOT SEE THE PURPOSE OF THE EYEHOLE LENS. IF THERE ARE AZIMUTH NUMBERS SURROUNDING THE INNER FLOAT, THOSE SRE NOT VISIBLE. IF SOMEONE HAS ANY PRINTED DIRECTIONS THAT WILL BE USEFUL.
