Interior of Hupfeld Helios II/25 Orchestrion
 The Piano with Harfe attachment is barely visible behind the roll changer. The xylophone is at the upper right, directly above the clarinet pipes. Note the bottom portion of some of the large bass viol pipes, which are visible at the bottom left side of the case. The automatic register controls are to the left of the roll changer, and allow individual voices to be manually locked on or off as desired. |
