In addition to serving the commandant, this aircraft was also made available to the Secretary of the Treasury as well. The aircraft served the Coast Guard well but was traded to the Marine Corps in 1945 for a Grumman J2F. The commandant’s executive transport aircraft by then was a Lockheed R-5O Lodestar, USCG No. 12453, acquired in 1942.
