I have had this music box for some time and have just put it for sale
on eBay.  It has been suggested that it is an early Forte-Piano type
with pins of different heights.  The reason suggested is that it has
a 4-blade governor fan and it takes 1 minute 20 seconds to cover one
revolution.  In my opinion, this could be because it is a 2-per-turn
cylinder.  I would appreciate any comments though.
