Jumpy pins (new one on me)

List,
   I tuned a Wurlitzer Spinet yesterday (yeah, I do have to go out to make
some extra money occasionally) that was 1/4 to 1/2 step flat. The type
without a fallboard. It hadn't been tuned in years!!!
   My question is this:
The entire piano had jumpy, sort of loose, tuning pins. Some were worse
than others, but they would all hold. There were a few that, when bumped
backwards, would go all the way down. But when I brought them back up, they
held.
   I could see no evidence of contamination around the tuning pins. The pin
block, unfortunately, had one of those app. 1/8" thick pieces of wood glued
to the top of it, so I couldn't check for pin block/back separation there.
   Before the piano came to Houston, it had lived on both coasts of Florida
and a couple of other places, not coastal.
   The only other time I've seen pins that jumpy was after some "tooner" in
West Texas had sprayed WD-40 on the pins and coils to clean off the rust!!
   Except for, possibly, the salt water humidity or block problems, I have
no other ideas. IMHO, the piano isn't worth trying to do anything to. I
explained the problem to the customer and advised them to start thinking
about getting another piano in the near future.
   But my curiosity is aroused. What could cause this on the entire piano?
Any ideas?
   Thanks.
