OHS, in concordance with the organ builder, affirms that the console is en fenêtre. Technically, all consoles are attached to the organ, by electric, pnuematic, or mechanical means.
The site https://fr.wikipedia.org/wiki/Lexique_de_l%27orgue offers precisions that I agree with. «Si la console se trouve intégrée dans le soubassement du buffet principal, on dit qu’elle est « en fenêtre ». My translation: If the console is integrated in the basement of the organ principal case, it is called «en fenêtre». That way the console is linked in all directions with he pipes.
In the instance of this JAECKEL organ, I differ from both of you. Your first picture shows a distance between the console and the bottom of the case, which is corroborated by the maker\'s photos. This console is not factually «en fenêtre». But the main detail that is worth mentioning and noting is that the \"abrégés\" are visible from the console up to the instrumental part of the case. (As there is a platform between the console and the case, we can presume that the pedals are also linked under that platform, to the corresponding pipes.)
