CF-AMB Stearman 4-EM Senior
Speedmail
(c/n 4016)
Five of these converted Stearman Model 4 were operated by Canadian
Airways in 1930 for
airmail routes. The front cockpit was converted into a hatch-covered
cargo hold, maximum
payload being 600 lbs, more than enough for the average mail run.
CF-AMB was withdrawn
from use in February 1933. Photo via General Dynamics.
