piano looks to be a 1925, as the serial # is in the 75,000

U.S.A," cast in the plate in the usual place you see the brand, in the
treble aliquot section, (See photo) (although this piano has front duplex,
but not rear aliquots.) I would be really surprised if there wasn't a
patent for this tuning system somewhere in the patent archives, but I'm not sure
where I would start looking or what search words to enter. Maybe you would
know.</FONT></SPAN></DIV>

think there might also be some confusion here because Wurlitzer
apparently used two different configurations for these iron pinblocks. The one
I am working on uses a machine screw with a relatively fine
thread to hold the tuning pin in from the back (or underside on a grand),
but you brought up a good point: there was also a design that used wedges, and
a tuning pin that was split at the bottom to accept the wedge, which wedge
could then be pounded in further to tighten the pin (which design I have
also seen in my travels, but unfortunately don't have a picture
of.)</SPAN></BLOCKQUOTE></DIV><BR></DIV></BODY></HTML>
