My wife and I will be in and around London for a couple of weeks in
July and I would like any suggestions as to museums of mechanical
musical instruments we could visit in July.

On a previous trip I visited a museum in an old church building which
had, among other things, a Wurlitzer theatre organ with roll player.
If I recall correctly, I walked there from Kew Gardens.  I believe it
was started by a Mr. Holland but that he died some time ago.

Does anyone know if this museum is still in operation?  If so, can you
tell me the address, telephone number, days and hours of operation,
etc?

Many thanks,
