yes, this is the present state of knowledge; Akanihin has a bit modified these statements saying that olive was standard up to 1935, 3B in 1935-37. However, both paints were found on one piece.
Hi Massimo. Thanks for the response. I'm not quite sure what you mean by that last sentence. One plane with both colors, or different planes with one or the other? It looks as if I'm going to go with markings for 1936, so based on Akanihin's comments, perhaps 3B will be the better choice?
Please, keep us informed of the progress of the work.
I'll post some pics once I've got some paint on. It'll be a while -- I'm just getting the engine nacelles and tail assembly installed. Then I have to try to summon up the courage to do the photo-etch spoked wheels!
