Was that a solid bridge root with a ship-lap joint, or vertically 
laminated? I've also been curious through this thread, about the new 
Steinways you've examined and found no crown in the mid-treble. These 
were pianos you were called in on presumably because of just the 
tonal problem mentioned in Terry's initial thread. Pianos new enough 
to convince you that they let the factory with deformed boards.

How many were these? And how many new Steinway pianos have you been 
called in to examine because of perfectly fine tone, in which you 
found the required crown. Or if this is too small a sample (being 
maybe less than one), compared to Steinway's annual output.  This 
ratio would answer whether the the disappearance of crown is 
system-wide and due to a procedural decision from the engineering 
department, or simply as John suggests, from garden variety 
"out-of-tolerance" work on the floor.

I'm also glad to see John back on the list.
