A Mortier organ that is missing in the book 'The Mortier Story' is the 80-key dance organ still owned by the Ryan family in Dublin, Ireland. This instrument – with presumably a serial number between 867 and 872, given the style of the façade – was acquired in the early 1970's by collector and dealer Emiel Baude in Destelbergen near Gent (Belgium). He removed the pipework in the side cases and replaced it by the percussion. Although the harmonic flute was still present, it was disconnected.
