It seems typical Warbird-operating outfits do not have strain gauges installed, nor do they need them to be certified for flight...

I contacted one of the head engineers of Vintage Wings in Ottawa, which operates about ten WWII fighters near my home, or various other 1930s single engine aircraft types (including one 1950s Sabre), and it seems wing strain gauges are not on their radar screen for any type of use or certification.

I wonder if any such strain gauge in-flight data exists for horizontal turns in WWII fighter aircrafts, either contemporary or more recent: The only data I have been presented with has been wing bending measurements that are for static on-the-ground tests...

It seems the use of strain gauges on the wings of these old machines is quite a bit more esoteric than I thought... As a practical matter, the limited access to the main spar might be a reason.
