Off topic for a moment but, do you know perchance what's going to
happen to XH558 at the end of this year? I've never had a chance to
see a flying Vulcan, and it's too bad I won't ever get to see one (nor
did I get to see the awesome display of both of he flight worthy
Lancasters flying together last year...).

Somewhat ironically the ones that can be maintained in ‘original' condition for longer may be the mechanical ones where replacement parts could be fabricated whereas valves and SSI TTL may not be able to be economically produced.
The point you raise is comparable to the fact that we'vve basically
flown the life out of the last Avro Vulcan, meanwhile here in my home
town we're still managing to keep an Avro Lancaster flying after all
these years.

Also, I realize anyone can infer where I live based on the statements
in this e-mail, hah.
