Good Morning:  There is a set of tuned sleigh bells (and maybe
even tuned cow bells) at the Circus World Museum in Baraboo, WI.
The museum is owned and operated by the Wisconsin State Historical
Society.

There are also many other mechanical musical instruments on the
grounds.  All are in excellent working condition and are demonstrated
throughout the day.

If you are ever in South Central Wisconsin, this museum is a _must_!
