From the ILUG exhibition in Gothenberg
A late arrival in the stand of Bäumer Aero G.M.B.H. was a Dietrich-Gobiet two-seater, with rotary  engine. The machine is, it is stated, intended as a sporting type, and is known as the type D.P.1.  Both in the shape of the fuselage, tail, etc., and in the matter of construction, the D.P.I is very reminiscent of some of the German Fokkers. The fuselage is of welded steel tube construction, and the inter-plane strut-,undercarriage struts, etc., are streamline steel tubes. A good deal of attention has been paid to ease of dismantling and erecting, but other-wise the machine is of no particular interest. The general appearance is shown in the accompanying photograph, and the quick-release mounting of the one-piece top plane is illustrated in a sketch.
