Kotykiewics etait le successeur du Peter Titz de Vienna.
Teofil Kotykiewicz a produit des instruments gigantesque.... http://www.harmoniumnet.nl/kotykiewicz-vienna.html
Un des instruments ( 21 jeux incl. 5 a tuyaux ) existe.
I have to switch to english, sorry.
We believed those giants were not built, only in catalogs. However, we found written sources showing a concert in 1884. But the largest one ( the 21 jeux) was never mentioned.
And only 2 weeks ago one came up and has to be restored.
Due to 'un procès' it is not possible to reveal the where abouts of this instrument, nor can I show pictures.
