Hi Robbie,  As far as I know, there is only one extant model 164
Wurlitzer.  The last I knew it was owned by the wife of Paul Turin,
whom I think lived in New Jersey.  I have some recordings that I made
of it several years ago.  Sadly, it was in need of a tuning but still
an impressive sounding instrument.  I saw and heard it last year at the
Band Organ Rally at Fremont, Ohio.

There was also one made for someone in the Southeast, possibly South
Carolina, that was a "reproduction" organ.  It may have been made by
the Lance Johnson Organ Company of Dakota but I'm not sure about that.
