WTF-Beta

I'd at least get a quote for at least re-stringing--new pins and new strings. All that work to keep 50+year old strings (especially bass strings) is not the best use of funds IMO....and since they'd be pulling the dampers out anyway, new damper felt.

Otherwise, CA the whole block, or spot treat problematic pins as needed.

I'd plan on the more complete job sooner than later though. A couple rough dry/humid swings can take a marginal block like you have now, to one that can't be counted on to get through a performance. (really replacing the block would be even better, but I understand about budgets)

A good $20k rebuild (particularly on a 9ft piano) hasn't been around for many, many years. $40-60 on that size piano if your doing action/block-board/finish. Good parts and people are expensive.

Poor Australia--reduced to a rounding error, lol

Moldex 2200n95. The 'k' basically has ear loops instead of head straps and doesn't give quite as good a seal.

I've been using them for a 25+years for sanding/finishing work. They are ugly, but they do form a much better seal than any kn95 and regular n95 mask I've used. No clue how effective any of these are against viruses, but if after a day of sanding (even with a light beard) my snots are clear vs mahogany...that's a good mask, lol.

Here’s the inside of one I’ve been using the last couple days. Shows where the potential leaks are. Clean shaven, I get a somewhat more defined line.
