Those who have read the book 'The Mortier Story' already know that very few Mortier organs have survived the times in their original state. Parts of many organs were reused in other dance or street organs. Thijs Haenen recently shared a photo showing one of the crankshaft's bearing blocks in his street organ 'Fata Morgana', in which the serial number 1029 has been stamped. So this is a part of the 101-key Mortier dance organ #1029 now located in Japan.
Organ builder Henk Veeningen used parts of various Mortier dance organs in the construction of 'Fata Morgana' but this is the only one with a serial number on it.
