Hello All,
I hope you don't mind indulging me in a bit of cross-Forum discussion?
On the Key Magazines Historic Forum, there is a mystery aircraft which is baffling identification. One of the possibilities is that it is a mail-carrier operating in Japanese controlled airspace (China or Pacific rim in the late 1930s). If Lennart is "on-line", perhaps his opinion might be worthwhile.
For that matter, perhaps one of you other knowledgeable people might venture a guess.
