Just curious, is the finish of the Liberty Belle historically authentic, I can’t find any WWII pics of this aircraft? I’m asking this, because the design of the pin-up looks very modern to me.

Other question I’m always asking myself about these warbirds: why are they today silver painted, as they were left natural metal during WWII?

Being painted silver protects the metal better than being bare metal finish, it didn’t really matter in wartime about that.
