National Air Transport  Douglas M-3  (N)C1000        (c/n   645)


                                        This image is so poor I was tempted not to include it, but it does illustrate the fact that NAT
                                        used machines other than Curtiss Mailplanes from time to time.    It shows an M-3 being loaded
                                        with mail.  (Looks like a very unorganized operation unless this shot was "staged").   This M-3
                                        was later converted to the popular M-4 status.
