This has been my experience as well. Back when I was servicing pianos out on
the coast, it was not unusual to find pianos with well-protected (D-C's)
soundboards that still had rusty and/or cooroded strings and tuning pins.

Yes. But here the D-C and the majority of the piano's workings are together
inside that nice, closed box.
