I have been following this thread about the double-keyboard Bechstein with great interest, since I happen to own one. I have it here in West Palm Beach, and will be bringing it to our booth at the national PTG convention this June. For now, though, I have posted some pictures, as well as a scanned PDF file of the complete history of the double keyboard piano, statistical information about how many were made by each manufacturer, and action diagrams. The PDF file is rather large, so I posted it on my site here: http://www.kraftpiano.com/Bechstein/double_keyboard.html You can download the PDF files and see pictures there. Enjoy! --Justin A.
