Andre,

It is the Hanriot HD-1, I'm doing a build thread on this site under scale models, GTM Hanriot Build. The full scale example is located here:

One of the problems is that it is hanging from the ceiling so is difficult to get close to. I've been in touch with the museum and they have been extremely helpful, but we are limited by the color variations caused by photo processing......

There was a fellow at one of our scale contests that had the American Airlines Stinson in that color scheme.....I'll see what I can learn.

Do you know where the airplanes that you are interested in are located?
