Yes it is a very rare aircraft. No flying examples exist. First flight in 1935.

Time for another clue: The factory was destroyed during WW.II, and the company did not resume production.

Koolhoven F.K.49?

S'land is correct:ok: You have control.

Thanks Bri.

I had a real beauty ready until I checked the list to find that it had already been done. This one, however, I could not find in the list.

Hey S'land, is that a Fairchild?

Sorry, not a Fairchild.

Norduuyn Norseman?

Indeed, it is a Norduyn Norseman. A Mk IV, to be precise.

You have control, sir.

Bri,

I've been offline for a while and so have only just seen the answer to your "twin Gipsy cockpit". In future, please warn us in advance if you are going to post such an ugly aircraft ;)

Even without the flat tire/tyre, I think it should be called the "Unkoolhoven F.K.49"

Good job, in my opinion.

Casa C-201 ?

Hi Bri - Sorry not the CASA 201. This aircraft was produced in the USA.

Convair 240 / 340, T29, C131, R4Y etc .... Keith ?

Hi Keith - It does have two big radial engines, but it is not from Convair. (Or Martin.)

It looks immediate post-war. I've ruled out Dee Howard and the OnMark Marskman, as the panel in the challenge photo looks like an original design. I was considering the Lockheed Saturn, but the over-head fenestration doesn't match. Is it perhaps a prototype?

Here is a clue which should make it easier.

Planegill's challenge
 

Possibly the Chase YC-122?

Yes, Mel has it. The Chase C-122 Avitruk. (I knew those windows would give it away!) You have control.

Thanks Planegill, yes it was the cockpit window configuration that gave it away.I was thinking the aircraft was earlier than the late 1940s and early 1950s. Here is the next one:-
