plate warping in 1877 Steinway B?

[Ron Shaffer]

I am certain the pinblock is at the exact height of
the original one. The piano has a full plate, but it
did not sit on dowels when the plate was pulled 5
months ago, nor was there a wooden spacer(I don't know
whether the plate was pulled previously - certainly
possible). I was told the tail did pop-up considerably
when it was loosened. Thanks for all the good advice.
