A non-Bréguet challenge - which plane is that ?

[Catfish]

Hello,

i am almost sure what it is, however i have not a good picture of it from the left, as it is shown beneath :

What i really need is the time of the photograph, if possible - or at least that it was not possible to make this photo before a certain time, e.g. pre 19xx.

Here it is:



I think it might be a plane from the Breguet challenge 419, but not with "Stahlherz" rotary, but an inline engine. Maybe Kees, Aquilius or Richardb know something about it - or maybe i am wrong in identifying this ? I wonder what the descending tube is, at the rear of the engine. I have only photos from a "Union" from the right side

Any help regarding the time of the photograph, or further info on the plane, would be welcome.

Thanks and greetings,
Catfish
