The appearance of this biplane is very German/Austrian from the immediate post-WWI period.
The three-view drawing seems to me a rather crude rendering of the 1919 Lohner Express I. This was the original 1918 Lohner 10.23 prototype (Lohner AC) rebuilt with an enclosed cabin for two passengers.
The Express I made some flights from Austria to Ukraine in the summer of 1919, and it was probably sold to the Ukrainian government. Eventually the Inter-Allied Aeronautical Commission of Control confiscated the plane bfore it could be handed over to the Ukrainians. The Express I eventually ended up in Switzerland.
More details can be found in Andersson/Sanger, Retribution and Recovery (2014).
Below a more detailed three-view drawing of the Express I from Keimel, Luftfahrzeugbau in Österreich (2003), p. 215.
