a Zimmerman Concert Grand Autoharp

"The Concert Grand is a very large autoharp, measuring about 20" wide by 30" long. It has 49 strings, covering four chromatic octaves, 6 bars bearing 12 shifters (10 active, 2 dummies), and it is said to be capable of producing 60 chords. The action of the Concert Grand differs from that of the Parlor Grand. Like the "All-Chord" above, the Concert Grand's bars can be situated in any of 3 different positions, each of which produces a different set of 3 chords per bar."

I was told by a 'friend' that he had sold one...after he sold it. "Gee, I didn't know you wanted one."..As far as I know, there are only a couple still in existence. I did acquire a Zimmerman #6 model in a 2nd hand store about 20 years ago...cost me $22, rather than the $1000 the big one would have cost....so maybe he did me a favor.
