Hi, Ron, Robert Wornum held the "Royal Patent Equal Tension Scale" a long time ago; the difference was, he used a single wire size for all of the unwound strings, resulting in quadrupled inharmonicity per octave. Wolfendon's published scale has changes for wire size, and I think the scale used in Mehlins corresponds with it (these two seem great when calculated for inhamonicity!) But, what a great thing: if one variable is lacking, ignore it and try your best. Was this a Scale 5? They're very nice instruments. I just read in Colt's _The Antique Piano_ that Pleyel (perhaps through Pape's influence [my guess]) had been so excited about wound strings that he built a piano with _all_ wound strings. Even a stranger idea, eh? Clark
