...Is this a limit on what you can reasonably do with eighty-year-old aircraft?..
Had a look at the (one and only) BBMF Hurricane some 50 years ago when it was overnighting at Leeming (?) prior to a display.
Every free square inch of the panel had a little red metal label on it: don't do this, don't do that, don't exceed 220 IAS and Lord knows what else. And the 'old' lady was only 30-odd years old then ! Even the ones I briefly flew at Castle Combe in 1942 were clapped-out and we were told to treat them gently.
