Paulin Aneroid Altimeter
- Joshua Gabriel Paulin, in Sweden, developed an aneroid barometer with an adjustable capsule that was suitable for use in altimetry. This example is marked, on its face, “PRECISION ALTIMETER / Patented” and “System Paulin / Stockholm” and “MADE IN SWEDEN BY C.E. JOHANSSON, ESKILSTUNA.” The outer scale around the circumference extends from 4000 to 9700 feet and the inner one extends from -900 to +4000 feet, and both are graduated to 10-feet intervals. The back of the case in marked "MADE IN SWEDEN A1217 PAT'D U.S.A. SEPT 9-19 APR 13-26."
- A gold label on the leather case is marked “The American Paulin System INC. 1220 MAPLE AVENUE LOS ANGELES, CALIFORNIA.” This company termed this model “The ENGINEER” and, in 1929, sold it for $125.
