I've compared the drawing with Richard Payne's descriptions in his "Stuck on the drawing board", but I can't recognize the type. Who can help to identify it?

Maybe it's the german design T-25-002.006 from the ArGe Airbus ?
Would be an explanation, that you couldn't find in "Struck On The
Drawingboard" ..
