Del,
There is a lot of this cooling which takes so long it might
be called "curing" that is mentioned in the publication of
American Steel and wire of the piano maker's conference in Chicago
starting in 1914. I lost my copy, if any one wants to sell
theirs I offer 20 dollars. If the binding is shot that is OK as
that makes it better to scan. ---ric
