Pitch raising on older pianos

[RustRazor@AOL.COM]

I have found that on an older, not-so-valueable piano, it may be futile to 
try and pitch raise.  The piano may hold a tune great at 100+ cents flat, but 
may be unstable at pitch because of an old pinblock.  In such pianos, (like 
those ratty big old uprights), the customer may just want the piano in tune 
with itself and uninterested in having a piano at pitch and definately 
uniterested in spending the extra money to do so.  so you may want to keep 
that in mind.
