Steinway flat board

[Wallace F. Wilson (WV)]

I recently inspected a 1989 vintage B that a customer of ours just purchased
-- won't say from where.  The board was FLAT.  Downbearing adequate in most
places, but not so much that it should squash the board.  Treble bridge
riddled with little cracks  by the pins.  Sound not that bad - a bit of
deadness in lower treble, but that's not all that unusual.  Ours is a
climate that is quite damp in summer (90-98 degrees, 90% + humidity) and
quite dry in the winter.  The piano came from New England.

My question: do they have a real problem that they should take up with the
dealer?  Is this common?  Acceptable if the tone is pleasing?
