I think there is some more research to be done on the names of the company, when I read

In Germany a different arrangement was made, and on 28 February [1911] the Deutsche Bristtol Werke with a capital of 200,000 Marks (half subscribed by the Bristol Directors), was formed to manufacture Bristol aeroplanes under licence and to operate a flying school at Halberstadt, supervised by Bristol instructors. The Deutsche Bristol-Werke later came under pressure from the German government to produce aeroplanes of new design rather than Bristol types, so the licensing agreement fell into abeyance and was formally cancelled on 23 June 1914.

Some points -

• When was the Halberstädter Flugzeugwerke GmbH founded ? According to Lange sometime in 1913.

• There never existed a Bristol-Halberstadt firm, there was Deutsche Bristol Werke and Halberstädter Flugzeugwerke, at some time parallel (1913 / 1914) but sperated legally

• The first Taube (I) seems from the picture to use the patents granted to Coanda in France, England, Switserland and probably Germany (not searched out) in 1911 / 1912.

• IMO the Roman numbers are much later allotted to different Halberstadt Taubes, to differentiate them.

I also read through the book of Werner Hartmann [Halberstadt - Luftfahrtgeschichte in einer deutschen Fliegerstadt], but it did not became more clear to me how the relation Bristol <=> Halberstadt was.

Consulting the indexes of Flugsport there are references to Bristol Eindecker in the years 1911, 1912, 1913 and 1914. Till 1914 there are references to the Halberstädter Flugplatz and 1914 brings us a reference to the Halberstadt Taube. There are no references to a Bristol-Halberstadt. In the volume of 1916 is the first reference (in Flugsport) to the Halberstädter Flugzeugwerke in the section Firmennachrichten.

Have a fine day.
