Hello All,
Aquilius,
Thanks for additional information and half a point. Winner or loser, I feel good - particularly with my internet fixed.
Anyway 0.5 is much better than nothing.
Unfortunately, the lack of good “paper” sources on early German airplanes is my problem. German books, especially these issued some time ago, are hardly available on Polish market. On the other hand, my primary (and the only) source
The Taube at War by P.M. Grosz proved to be not very accurate in this case.
The author introduced only one type of Halberstadt Taube equipped with four-wheel undercarriage. Curiously enough, there are four photos of this plane (page 12 and 13) and all show rather classic "taube" design with
in-line engine. Not a single word about aircraft powered by rotary engine. By the way – picture No 49 is very similar to the challenge photograph.
I was trying to find something more on Halberstadt Taube on web sites but the information given by one of these sources was even less accurate (and it was not Wikipedia or something like this).
Thanks again,
Regards
Marek
