A capital or upper key first letter (and in the middle of a sentence) indicates (in German) this being a subject (grammar) and the "-n" at the end indicates the plural form of the word "Keule" (bat or club).

If you read my post, I offer up a possibility not a conclusion.
How would anyone know how the word "Keulen" was used in the original documents based on CJE's first post?

Objection accepted. Nevertheless, even JCE spelled it as "Keulen" with a capital/ upper key "K", thus leaving my explanation still valid.

Thanks gents,

As I assumed, it confirms that the moving surfaces had a symmetrical profile (just like a baseball bat -> Keulen), so that they could be mounted indifferently on the port wing or on the starboard wing.
The same goes for the rudders and tailplanes.
