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  CF-AMB was withdrawn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.
