I am looking for somebody who could provide detailed information on a
Harmonium, built by  Prince and Co, Buffalo NY, in the 1850th. The
instrument is labeled " No. 20,522 / IMPROVED MELODEON / MANUFACTURED BY
/ PRINCE & CO / PATENTED, DEC. 28th, 1846 ".

I am interested in all information available about the instrument, the
manufacturer and what's about the value of the instrument today.
I have a book " HORTON PRESLEY : Restoring & collecting Antique Reed
Organs ". Fig. 1-2 and Fig. 21-1 in this book are showing instruments
of the authors collection looking most similar to mine. Does anybody
know how and where I could contact Horton Presley?

Thanks in advance

Christian
