There is the obvious choice: the MBSI maintains a mechanical music
museum in Norwalk, Connecticut, about an hour or so from the Big Apple.
Special guided tours for members on Sunday, open most days.  Check your
MBSI journal for details and phone numbers.

I'd invite you to my place, but New Hampshire is a _tad_ outside what
I'd consider a reasonable drive from the NYC area. =)
