Alaskan Airways
Stearman C3B NC5415 (c/n 121)
American Airlines used a fair number
of Stearmans in the lower 48 states for the carriage of mail.
Clearly this one was seconded to their Alaskan Airways Division. The
machine carries the somewhat
obtuse name of "Paystreak". It
was built as a C-2B and converted before this photo was taken to
C-3B
standard. This image is from the archives of the Museum of
Transportation & Industry (via Lars
Opland).
