During the Great War it was already customary to present new projects for evaluation in the Eiffel wind tunnel. For this purpose wooden scale models were made which were examples of the art of woodworking. Unfortunately most of these wooden wind models are gone, as presumably this one.
The original has nothing written on the reverse so what I write is very hypothetical. This is a triplane, a configuration seldom favoured by the French. There are only a few Nieuport triplane prototypes with different configuration of the wings. This wing model has a full width wing in the middle with a smaller wing above and below. The streamlining of the single seat machine is extreme, almost impossible to realise in practice. The whole engine is here buried inside the nose section. As this was surely a water-cooled engine there should be somewhere radiators to cool the engine, otherwise overheating would quickly start. I judge this machine could be from the period 1916 - 1920.

Although colour photography was possible in 1913 and earlier, there are no cards in colour. Thisone has apparently been handpainted.
It shows a scene in Austro-hungary sometime in 1913 with a Lohner Pfeilflieger biplane. The name Pfeilflieger (Arrow plane) hints at the considerable sweep back of the wings, which is unfortunately almost not seen in this view.
The exact identification of the machine is a Lohner-Pfeilflieger Type B Serie H2, identified in the A-H Army as the Lohner B.I.
In 1913 the A-H army identified individual Lohner B.I machines with names starting with the letter B. Hence the name Bella.
This particular machine was delivered on 9 March 1913 (Lohner works number AD 212). Per 8 February 1915 the A-H army numbering system was changed and 'Bella' got the id. 11.11.
As these Lohner Pfeilflieger were apparently very stong and resistant to the war conditions, 16 B.I machines were dispatched to Fischamend to be fitted with a stronger wing and dual control, for use as trainers. Again the machines were renumbere, so 11.11 became 73.11 and was identified by the A-H army as a Lohner B.I (Fd), where (Fd) is the abbreviation of Fischamend, in full the K.u.K. Fliegerarsenal Flugzeugwerk Fischamend.
One specal mention for the very large tail wheel fitted to all Lohner B.I machines.

Engineer Hermann Ruthenberg from Berlin (Weissensee) designed and built a dirigible in 1909. It was small with a gas bag of 1200 m3, length of 40 meter. Power was delivered by an equally small 24 hp Benz engine driving a four-bladed all-metal propeller.
This Ruthenberg dirigible was exposited at the 1909 ILA [Internationale Luftfahrt Ausstellung]. Later this design was identified as the Ruthenberg I as a larger dirigible (Ruthenberg II) on the same principle was built in the next year. The gas bag was enlarged to 1700 m3. In 1913 Ruthenberg buillt his final (Ruthenberg III) dirigible, powered by two Fiat engines rated each at 75 hp.
There is right under the front side of the envelope a triplane elevator as a characteristic of this dirigible.
An overenthusiastic stamp collector has used scissors to cut off the stamp at the back. I decided to leave it as is and not try to fill it with the editing tools of today.

The textwriting is beautiful, but too difficult for me to read.
