Faber-Castell Map Measure Sold by U. S. Blue Co.

Description
This metal map measure consists of a slender tubular handle attached to a dial with a wheel protruding from the bottom. The white paper dial is covered by glass and has a thin blue metal arrow attached in the center. The arrow moves as the wheel is traced along a map. The outer ring of the dial is marked by threes from 0 to 39 for converting inches to miles or inches to verstes (a traditional Russian length measure equivalent to 3,500 feet). The inner ring is divided by units and numbered by tens from 0 to 100 for converting centimeters to kilometers.
The center of the dial is marked: Made in (/) Switzerland (/) U.S. BLUE CO. (/) CHICAGO. The metal between the dial and the wheel is marked: F C (/) DEPOSE. The Faber-Castell logo of a castle is between the letters F and C. The letter B is scratched into the back of the instrument.
The German company A. W. Faber was renamed Faber-Castell in 1905. It sometimes manufactured products in Switzerland, and "depose" suggests that the firm filed for a trademark there. U.S. Blue was presumably a blueprint company located in Chicago; it also sold slide rules from Hemmi. The Eugene Dietzgen Co. also sold this instrument, charging $2.20 in 1926. Alfred J. Betcher (1887–1971) owned this example, perhaps purchasing it when he was studying at the University of Minnesota (1906) or at West Point (1907–1911). He was commissioned as a captain, served at posts in New York, Vermont, and Kentucky, and retired in 1939 at the rank of lieutenant-colonel. In 1940 he was elected mayor of Canajoharie, N.Y.
