In all honesty, that phenomenal appearance of my pilot's face must have been (at least) partly a trick of the lighting, at that moment - because, out of a whole parts-box full of those 72-scale figures, I've never noticed such realism on any of them before. Of course, until I snap these (macro) closeups, and enhance them on-screen at 20x life-size, I don't know what the hell they really look like, anyway!
But these are definitely "Italeri plastic", as you say - each with the separate arms and upper/lower body parts, that you assemble in the desired pose - though maybe from their Heinkel He-111 kit, however all Italeri 1:72 aircraft figures are the same, IIRC. If I can determine anything(s) more specific, I'll certainly let everybody know.
Meantime, I'll definitely "wear" the compliment - and with great pride, coming from you, buddy!
