Thank you very much!

@aymodeler: thank you for the feedback and photos. If the panel is somewhat smaller than I thought (see John's reply) and if the pedals are wide, perhaps the pilot position is not as uncomfortable as I thought. Oh, and photos are always welcome

@bunsen: I hadn't thought of checking museum websites, as I didn't think that someone would provide a 360° view of a cockpit. That's a great source of information, thank you! By the way, both links seem identical to me. Am I missing something?

@john534: Thank you, that's exactly what I was hoping to find. If you don't mind me asking, where did you get those figures from? If it's some book or publicly available source, then it may come in handy in the future, both to me and to everyone else doing a P-47.

Anyway, I printed a paper template of the instruments panel to the scale size (27.5" / 5.75 = 4.78" = 121.5mm) using a template that I already had (even though it lacked size information, so I had no idea how big it had to be). Then I placed fuselage former F3 and the canopy one on top of the other (leaving a gap to account for the thickness of the sheeting), and finally played around with the position of the panel. The former should be of the correct size and shape (according to the 3-views that I have), but the canopy may not be 100% scale, so I may have to find (or make) a more scale canopy later.
Attached is a picture of the result. I'll also attach a few photos that I used as a reference. Opinions? Does it look reasonably close?

Andrea.
