Reading a Board

But then you don't know what was installed when the board was replaced, nor 
what was done with the bridge cap and plate height, so you have to judge 
from what you can see, measure, and hear at the moment. It needs a board, 
quite possibly bridges, and, plate height reestablished in the process.
