Guys
With ref to the early Do 17,

I guess the R could also stand for Reserve, that is a reserve unit.
The code 80+B14 works fine with me, but what about the aeroplane in front, 80+B3K? What kind of stafffel is referred to with the letter K or what else could be the meaning??
With the regard to the French experimental aircraft I have seen it or something like it, but can't put a finger on it unfortunately. The Farman 230 was a pixie and I don't think this one had had any military service.
Large numbers of French light civil aircraft was impressed by the Armée de l'Air and used for liasion duties, but those I have seen did combine the civil registration with some kind of roundel.
Cheers
