Now.
The airliner in the background is definitely a turboprop, we can see the prop blades. It also looks military (dark grey). I'll say 4 blades (and not 6).
It is not an Antonov 140 (wrong air intakes), nor a Fokker 50 (wing is too high), nor a Fokker F27 (which has no air intakes on the wing root), nor a Dornier 328 (wing root too short)
What's left? ATR42 & 72 and EADS-CASA CN-235 (not C-295 because of blade number).
Now, checking the various liveries on JetPhotos.net and comparing, I think I can read "Armee de l'air" on the fuselage.
So I'll say the turboprop is a CN-235, the clue is the "frog" and the kit plane is French.
Am I right?
Edit: after looking through all of these
Experimental/Kitbuilt Piston Airplane Manufacturers - Used French Airplane Sales at GlobalPlaneSearch.com I think I can safely call it a day....
