    I first sent this posting with pictures attached, and it has not 
appeared yet, on the list, so I am re-posting it without the pix.  How do I 
get to the "images", wherever they are, to see if the moderator has posted 
them yet?

Anybody got some stories about how they replaced a pinblock, or soundboard 
on one of these?  I saw this one yesterday.  I got a call from another tech 
( I found out that the call went from the customer to one tech, to another 
tech, to me, now I know why).  The pinblock is two tiered, and the plate and 
the block are mortised into the sides of the case.  The soundboard has a 
beautiful scrolled molding around the perimeter, that would be difficult to 
remove without damaging, if one would try to remove it, I would guess.
    Somebody restrung the piano, and put on new hammers, at some not that 
distant past.  They must have determined that the board was flat, and needed 
to have more downbearing, so they put shims under the strings, right behind 
the front bridge pins.  The strings sit off the surface of the bridge at the 
rear pins.
    The hammers are huge.  The centers are sluggish with vertigris, knuckles 
flat, etc.  Rocker capstans, I think is the right term?
    Overall, I was surprised that the sound of the piano was pretty good. 
Bass full, no dead strings.
    Anybody have an idea of the value of this 8 1/2 foot beast?  Serial 
number is 10433 (I found it stamped in the keybed).  Any advice on the 
pinblock and soundboard would be welcomed, as well.
