The Mother of all Bellyrails

Del,

This is certainly a fascinating and exciting find. I'll be looking forward 
to whether you can determine what kind of soundboard crowning method was 
used. Seems like it would have to have been rib crowned or it would have 
lost crown and fallen apart decades ago without the full support of the 
liner all the way through. Do you or anyone else have a laundry list of 
manufacturers who used the rib crowning method in the past or even who does 
today?
