... It'll look far more like a photo of the real thing than what we have now. It likely will have different height settings for the sight head in different planes, thanks to the real sight's height-adjustable vertical posts. ...
Sounds really good!

Speaking of gunsight height, I just wonder if they were really as low as they're modeled in IL-2; often target evades "zooming" and this way it offers a good firing solution,
but below player's plane nose. Lately I got some successful hits aiming well above an enemy plane that I couldn't see, relying only on instict, but was it so also the real thing? Or, as you mention, developers 'hunkered-down' position to hide cowling polygon gaps? And historical layout was higher? So to really help also during dogfight?
Lately I noticed, for instance, how TD improved N1K in 4.13: player may rise at will in his cockpit without seeing any inconsistency in his plane nose and fuselage (Shiden has big sides), on the contrary of previous, original one, which showed huge gaps when raising POV.
Sorry for the long digression (and all rhetorical questions).
