Bloch MB 161 as Testbed for What?

Hi friends,

the attached picture is from airwar.ru, but the text there (google-translated) gives no special reference to that picture. You clearly see the inner port engine is something different than usually. It looks like being an X-shaped piston engine. Could it be the French captured a Jumo 222 and subsequently mounted it on a MB 161 for testing? Or what do you say?

The big aircraft in the background is a SNCAC NC 211 Cormoran. Yo can give a guess for the small one, but for no need.

Thank you for answers!
