This profile is spurious. Someone came up with this s/n for the Martin 139WAA at the Air Force Museum. However, the plane is unidentified, and was given to the AFM by Argentina. The plane has been restored to replicate a YB-10, s/n 33-146. Since the aircraft has no known identity, I profiled it as the aircraft replicated and the photos are on that profile. Daniel Compton had a photo on 33-0139 and didn't know where the profile originated; he has moved his photo with mine at 33-146.
I suggest the spurious profile for 33-0139 be deleted.
