I work on several pre-modern pianos and the boards still sound quite alive as well. However, it would seem that the soundboard performance requirements for very low tension scales, as these all are, would be somewhat different from those of more modern instruments. I assume that would have manifested itself not only in the crowning procedures but the ability of the panel to expand and contract without undue compression stress. Comments?

I'm just starting a late 19th century 8'6" Viennese piano that is in original condition and will still knock your socks off. The only ones I find which die are very late 19th and 20th century pianos with soundboards installed with "tight" crowns, particularly compressed crowns.
