Andrew,

My first guess is that the plate is mounted too high. I've seen this in more 
than one D that age. If memory serves (hah!) the factory spec is 7 5/8" plus 
or minus 1/8". I'll bet you find the string line higher than 7 3/4. The 
pinblock will still be in the same place, though, and shimming up the action stack 
may cause the drop screws to drag on the pinblock. The hammers are probably 
close to nominal, so the shanks are probably way above the cushions, which will 
affect repetition. 

You're probably looking at a combination fix. You can probably shim the stack 
up a little. If the drop screws drag the back of the pinblock (behiind the 
cornice) you can plane it from underneath (avoiding the cornice). You may need 
to build up the rest cushions. Otherwise, a set of hammers that you bore 
yourself, at which time you risk a change in the sound he selected the piano for, 
unless you're confident in your voicing skills.

Good luck and let us know,
Bob Davis
