I have a part overture box by Ducummon Girod for sale.  It plays four
turns on a fat cylinder.  Exposed controls, with tune sheet.  Early box
c. 1845 and mechanically in nice condition.  I have posted a video on
YouTube.  Just search for videos by brianchesters or ducummon girod and
you will find it there.  It is one of the highest quality boxes I have
had in some time and, despite the age, the comb is perfect.
