It would require knowing the speaking length as well as wire size. and that assumnes the wirte sizes are original. </BLOCKQUOTE></FONT><FONT COLOR="#000000" style="BACKGROUND-COLOR: #ffffff" SIZE=2 FAMILY="SANSSERIF" FACE="Arial" LANG="0"><BR>

The 1878 Stwy Model B I rebuilt Had a pitch of A-458 and other writings (in our PTJ) and elsewhere varify that this was a pitch experimented with. Tension will be your biggest clue. At A-440 an average tension in many pianos will be in the 145 to 160 lbs. Some have huge tension lumps in the middle. Bu at least some idea of what was intended can be observed.<BR>
Don't get to hung up on a perfect original pitch level. If you're restringing the piano take the measurements and consult with Del. He has probably the most experience in this dept. and has been helpful to me in the past in this regard.</BLOCKQUOTE></FONT><FONT COLOR="#000000" style="BACKGROUND-COLOR: #ffffff" SIZE=2 FAMILY="SANSSERIF" FACE="Arial" LANG="0"><BR>

Hi all.<BR>
<BR>
A point of curiosity here. Shouldn't we be able to reverse engineer this <BR>
scale to determine what the proper pitch should be? Normally I wouldn't <BR>
reply and defer to my more versed associates. But, no one replied so I ask <BR>
the question. It seems like some of the equations that John Travis provides <BR>
could be modified to answer this question. Perhaps I am over simplifying <BR>
the problem. Just an question.<BR>
