The thing about that is that they will all still have wear and tear. I've been fortunate enough to be able to play around with lots of restored warbirds, and they show plenty of chipping, etc.
Not my photos, but some resto birds at airshows:
Above - Comemmorative Air Force Hellcat. Note exhaust staining and chipping on windscreen frame as well as leading edge of the wing just inboard of the gun.
Above: Planes Of Fame's Tigercat with exhaust staining, discolored panels and uneven paint depth/walk wear on the wing top.
Above: Planes of Fame's A-36 flying with a P-51B that shows wear on the bottom of the star and bar marking.
Above: This Spitfire is super clean but still shows paint stripped off the front edge of the cockpit dooor panel, streating from the exhaust (and possibly fuel filler cap) and dots of discolored paint on theunderside of the leading edge.
Above: Lots of tonal variation on the wing surface of this B-25
Old Crow here has plenty of chipping on the leading edge of the wing.
And because undersides almost always show more dirt than topsides, here's Duxford's B-17.

I can say from sitting in the cockpit of the Comemmorative Air Force's Bearcat that the seat is pretty worn, the horizontal stabilizers had plenty of leading edge chipping (to primer and bare metal) and showed wear on the spring-loaded panels that kick in for steps, as well as bare metal on the trailing edge where pilots climb in.
I've also never seena propeller that had an unworn leading edge.
That said, I have watched a pilot land a P-51D and then spend the next 10 minuteswiping the exhaust staining off the polished aluminum, but there was still a fair amount of wear on that plane.
If it's flown, it's worn. Even the Blue Angels, Thunderbirds, etc.
