Hi Sturm 78,
sorry, I didn´t notice Your question in July.
To Your first motorcycle. I think it is a captured Belgian FN type M 12, not the very similar Sarolea 1000, because the drum box is obviously on the left side (not visible).
The motorcycle on Your second pic is a Belgian Gillet-Herstal type 720 AB. Here a pic of this motorcycle, also captured (source:

Best regards
Bert
