I really do not know what to say. I was just about to give the answer and skytrain10 gives it for me.
It is indeed the Gruse BO 15/1, an attempt to create a "People's Aircraft". It was built by the August Gruse Maschinenfabrik and had a Köller m3 18hp engine driving a pusher propeller. It was a single seater with an operational weight of 306kg and a 108kg empty weight. My understanding is that there was only one built, registration D-YOYF, and that it was flown by Ernst Udet
You have control
skytrain10.
