Casella / Maker to the Admiralty / & Ordnance / LONDON / Compensated / 2311.” The outer scale around the edge of the face indicates altitude in “Mètres.” The inner scale indicates pressure from 63 to 70 centimeters of mercury, subdivided to half millimeters; another scale indicates altitudes from 300 feet below sea level to 15,000 feet above. A curved thermometer reads from -12 to +55 degrees centigrade. There is also a leather carrying case.
