Thanks for the input!  If you are correct in that it is the quality of
the glue joints on the ribs that makes the difference, then your final
paragraph affirms Hal's observation.  That is, the Wurlitzer's inability
to hold a tuning is due to a failure of the soundboard's construction.  

I've not read anything on the 'net about a follow up on this particular
problem.  Any news?

BTW, this is a fine addendum to my education.  Keep the good stuff
coming!
