This is about 2/3rds to 1/2 of what I would consider optimum rib crown 
for this pianos. So at least in this case a panel crowned soundboard has 
survived a few years after leaving the factory.

      Hey John
  A very good pictoral demonstration of what effects the bridge is having. I 
don't see any signs of cracks in the pictures. Why was this board torn down? 
It had fairly healthy residual crown for a board for an  East coast piano of 
this vintage. Was the tone suffering or did the client simply want to start with 
a fresh board & every thing else& optimum tonal performance? This is the 
first S&S board I've seen with any crown left after it was seperated from the case
    I also have an 1960 L ( calif. Piano) in the shop with very healthy crown 
as well & it sounds great. It has about a 45 ft' crowm in the shorter ribs 
about 60 to 70 ft. in the longer ones. Strings, finish & action work. Easy 
rebuilding.
  Thanks--Dale
