Andrea,
After taking a closer look, I tend to agree with your current assessment after all. The plane I photographed is in a museum that is not too far from me and they have open cockpit days where they let visitors climb into the cockpits of many of the planes (none coming up in the near future though). I know it won't help you now, but I will let you know the next time they have one, and if you have other questions, I will try to get the info for you.
By the way, your English is near perfect as far as I can tell ... I would never have guessed you were not a native English speaker
