About 3\4 zoom will make the reflector plate scaled to real world in your monitor. At which point you no longer have any peripheral vision. The artist looses "coming and going" trying to balance the proportions on the views.
Looking for cockpit photos of P40, I noticed that the effective eye center of the N-3 gunsights was different in photos with an obvious 6ft or taller pilot. And in the real war with different gunsight types and sight heads. The only N-Series gunsight shown correctly in our P40 is in the P40C which was refitted as quickly as N-3 with Curtiss right angle sight heads were available for the AAF and AVG. The rest are the Aces High generic rendering copy of N-3 seen on the Internet issued in other manufacture's planes during WW2. The N series of gunsights were procured by the AAF and issued to aircraft companies who created their own sight heads or purchased them and fitted them in the factory. Curtiss built their own sight heads to fit their P40's.
Modern rebuilds of P40 with N-3 mounted, are not Curtiss sight heads and mounts unless the re-build team can show you Curtiss stamps or documents. Most are N-3B or N-3C bodies with non-Curitss sight heads. Here is a museum restoration with an N-3C body and what might be a Lockheed sight head.
