If you have the same serrations on the wood that is just the original 
glue, which mean the ivory head has separated cleanly from the wood, 
probably owing partly to repeated changes in humidity and partly to 
the stress of being played -- the ivory at the extremes of the 
keyboard tends not to come loose.

In a case where the ivory has come away clean like this, it is often 
enough just to damp the original glue and let it soften for a few 
minutes and then clamp up with the heated cauls.
