Thanks Graham! Don’t know if you’ve seen my other oldie in the trim shop - the 1970 Plus 8? It’s now back in its original Indigo Blue, will be there next Monday to see progress…
I have now. It's presently tucked in with lots of others in the "Aero" shop (as was). Can't get close to it, for the moment (at least not with a string of people in tow!)

I'm in on Monday - 2 tours.
