French/German Mystery Ship?

[FlyingCoffin]

When in France in 1961-63 i saw in a museum a WW2-era 2 seater open cockpit radial engine bipe. The gunner had 2 coaxial MGs. The museum had no specific info but that it was supposedly German & pressed into FFI service in 1944 (rondels added).

I admit the description is sketchy. I can find no pictures online that match, hardly any pics of French recon types at all. Any clues? Maybe it was a French type that the Germans captured & then reverted to French service.

Pics of fighters & bombers are everywhere but the recces & such seem mostly sorely neglected.

Dornier Do22
Heinkel He114
Heinkel He60
Heinkel He59 (2 engines)

Where in France is the museum? I will be in Paris in 2 weeks and I might be able to look it up.
