<!doctype html public "-//w3c//dtd html 4.0 transitional//en"> <html> Jack, I have serviced two but can only recall where one of them is at the moment.  James & Holmstrom full upright, serial number 15501, built around 1909.  I haven't seen the piano for three years, so I don't remember all the specifics, but it had about 88 keys.  It would transpose two 1/2-steps either way.  The action was constructed without any breaks for the action brackets to keep the stickers evenly spaced throughout, and the whole keyboard would move sideways with a wheel under the keybed so the capstan screw would operate the neighboring sticker.  There is a little indicator needle that shows which position the keyboard is in. I made a mistake the first time I tuned this piano in 1992.  It was about 15 cents sharp, which surprised me, so I lowered it to pitch.  Only later did I realize the keyboard was shifted one position, so technically the piano was 85 cents flat, but I never changed it.  The transposing feature has not been in operating condition as long as I've been serving the piano.

And any other make that you may know of.    I  would also like  specific information  such as number of keys, brand and age ect.    We may have a Heintzman that will transpose one entire octave on exhibit at the upcoming T.S.A. Regional Conference Oct. 11-13 in Dallas.   Thanks, in advance.   Jack Wyatt</blockquote> </html>
