Well, Marek seems to have fixed his computer problems and Richard was carefully reading the posts of the Röver-challenge #111.
Unfortunately Lewis, you have been on the wrong track.
But some more facts to our challenge plane.
Maybe I should let the pictures speak:
Richard is right. Only the "Bristol-Halberstadt Taube I" had this typical Coandă-style undercarriage. But so far I know it was not powered by an inline engine. Looks like a 7-cylinder Gnôme/Oberursel of maybe 70/80 hp.(differences in this and questioned picture is the missing bridge below the wing)
All further developements had a two wheel landing gear. And responsible for Type III & IV was Dipl.-Ing. Karl Theiß who came from Albatros in the second half of 1913, when the Halberstädter Flugzeugwerke were formed out of the Deutsche Bristol Werke - seeing this aircraft this is no big surprise.
The Bristol-Halberstadt Taube I was mainly a Bristol-Coandă Monoplane fittet with Taube-wings. So far I know only a few copies were used in the company flying school.
It was designed (or modifyed) by the swiss Hans Burkhard in 1913, who flew with Nieuport, worked for Rumpler and then Bristol, where he should redesign the Bristol Monoplane for using the german 100 hp Mercedes engine.
I think the result was the "Bristol-Halberstadt Taube II" with two-wheel landing gear, but I can not prove this with a picture.
