Hmm... I was convinced it was a Bell X-1, but it seems the shape of the top of the fin is wrong and the nose isn't pointy enough... And are those intakes beside the cockpit? OK, not exactly a Bell X-1 then...

Perhaps a change of scale is called for. How about the Douglas XB-43 Jetmaster? More particularly the (possibly unbuilt) A-43 version with eight machine guns in a solid nose.

He said it was a project.

Therefore, in my book, it wasn't built.

I think it's something to do with quiet attack aircraft.

Bingo! :)

I hope he's OK now Hesham.

Looks like the Soko P-2 Kraguj mate?

Well that proved suitably elusive... not! Well done.:)

Thanks Kluseau!

I'll say open house for the moment...
...but in the backgound, I'm looking for a silhouette.

I gave up on the silhouette.
A photo instead...

Good afternoon to everybody (or whatever the time is in your country)!
It looks tremendously like a Potez 25/47....

Very close Carson. The second aircraft of this designation looked like this:
