I know it’s probably not the right answer (wing and landing gear all wrong), but because we’ve got to break the ice and start somewhere:
Neman KhAI-5 PS-5? (civilian version of the reconnaissance R-10)
The R-10 had a M-25 engine, this one was powered by Pratt & Whitney Wasp and later by a Twin Wasp. 
It looks to me as like a Vultee V 1, my dear Mr. Sergej.
BTW: Do you have some supplementary time on your disposal nowadays?
I believe you might be right, my dear Mr Librarian.
Our mystery aircraft does indeed look like a Vultee, as can be seen from the following photograph…
And judging by the slight differences from the production model V1A (gear, windows, canopy) I’d say this is a picture of the prototype.
Indeed it’s a modification of the Vultee V-1, in its history it had at least three names and three registrations.
The last destined task was to go to spain into the civil war, but not it its fate.
And yes I have time for our great game, for at least a week!
Ok, I just got confirmation by looking at the registration number visible in the picture - this is indeed the Vultee V1 prototype, tail number X12293.
And this also fits the other details or dear Mr Sergej told us: the plane was initially known as “Cord-Vultee V1”, because it was built in Glendale in hangar of the financial backer of Vultee, E. L. Cord.
Then it was modiffied to V1A standard (cockpit and landing gear as well as powerplant) and sold to American Airlines.
In 1937 it was sold to the Spanish Republican Army, but instead it was flown to France and re-registered as FAQAP, so it never made it to Spain…
Good work, but it’s not the Cord-Vultee V-1 and it’s an other tail number.
Research on one of the founders of the Airplane Development Corporation,
the predecessor of the Vultee Aircraft should lead you the proper solution.
Well, let me see… As far as I know, late Errett Lobban Cord, who had made his money as a highly successful car salesman, had bought the run-down Auburn company in 1924 and followed this with the purchase of Duesenberg in 1926. In 1929 he formed the Cord Corporation, which included by this time Lycoming engines and Stinson Aircraftas well…
Good Lord, my dear Mr. Sergej – are you suggesting that our mystery flyer actually is the Stinson M?
I apologize, but I never heard of the Stinson Aircraft Company before.
My primary source on the Vultee Aircraft Corporation (Wikipedia) says:
Gerard “Jerry” Vultee and Vance Breese started Airplane Development Corporation in early 1932
after American Airlines showed great interest in their six-passenger V-1 design. Soon after,
Errett Lobban (E.L.) Cord bought all 500 shares of stock in the company and
Airplane Development Corporation became a Cord subsidiary.
So you should try to find this plane through researches on Gerard Vultee or Vance Breese.
Oh, silly me! Actually you are pointing to the Michigen Model 1, also known as the Breese-Dallas Mod 1 Racer? How shortsighted I was! Please accept my request for forgiveness. :oops:
No problem Librarian, I have great expirience with shortsight.
This is the correct solution! Here is the story of our bird:

It’s your turn!
Oh, thank you very much for your compassionate stance, my dear Mr. Sergej. I have to admit that your task indeed was a feast for the sight and a charm for the mind, which it is impossible to exaggerate. 
And now something completely different, honorable ladies and gentlemen. Yes, I know - quality of this snapshot is not the best one. Nevertheless, it will be valuable for our intentions. Therefore, tell me, please – what is the brand of this airplane? 
I have no idea what that thing is, but Dear God it’s UGLY!
Anything that ugly, which clearly had so much effort put into making it look like that, suggests it has a French heritage and, given its distinctive ugliness yet endearing style, I’d say it was Citroen’s attempt at an aircraft.
Well, whatever this aircraft is, judging by the markings, it’s flying in the pre- Civil War Spanish air force.
For a brief moment I thought it might be either a Junkers W34 or one of the few Blériot-Spad 111, but a second good look convinced me it is neither…
That means we just have to dig deeper, and maybe the answer will become apparent.
Oh, never mind, I was searching in the wrong place again…:rolleyes:
It’s actually an Argentinian Ae MB1/2 “Bombi” built by Fábrica Militar de Aviones.

Thank you Mr Librarian, I really enjoyed the hunt for this interesting aircraft.
Later Edit:
Ok, in continuation, here is my own little offering for this thread.
What is the name of this machine?
I’d say it was Citroen’s attempt at an aircraft
Although, my dear Mr. Rising Sun, that previously presented airplane was not required to transport a farmer, a sack of potatoes, a small cask of wine and a bucket of eggs (without breaking the eggs!) and midwives like that notorious Citroen 2 CV (which is evidently deeply appreciated by you ;)), it actually shared one common thing with the good old Deaux Chevaux – almost incredible versatility and durability. Unbeliveably, but that machine was in active service even in 1944!
Thank you Mr Librarian, I really enjoyed the hunt for this interesting aircraft.
Oh, not at all, my dear Mr. Wingsowrath – the pleasure was mine.
What is the name of this machine?
Although I do know that over 2000 military and civil airplanes - based either upon original or licensed designs - were built in Romania between the Wars, this one is unknown to me. Yes, to certain extent it surely looks like the IAR 24, but on the other hand that registration (YR-IGR) is absolutely unmentioned in the Romanian civil aircraft register:
http://www.goldenyears.ukf.net/reg_YR-.htm
Well, we will be obliged to consider all availabl options, and that gradual, slow but sure approach is the best one in these situations. Therefore, would you tell me, please, my dear Mr. Wingsofwrath, was that mysterious airplane actually produced by the Societatea Autonomă Industria Aeronautică Română or not?
Ah, my dear Mr Librarian, I can tell you that the resemblance to the IAR 24 is not accidental, since the machine pictured comes from the same manufacturer, as you accurately guessed, albeit it is a somewhat more obscure design.
Other than that, I can only wish you good hunting!
Thank you very much for that highly important information, my dear Mr. Wingsofwrath. This time we are absolutely sure that this machine was not produced by Intreprinderea de Constructii Aeronautice Romanesti, or Societatea pentru Exploatări Tehnice.
However, I have an additional question for you. You see, that mysterious machine obviously has an air-cooled radial engine. However, I still don’t know what the brand of that engine really was: domestic variant of the Gnome & Rhône 7Kd (I.A.R. K7) or perhaps something else?
Ah, Mr Librarian, I am truly impressed with the extent of your knowledge in terms of aeronautics. I know many Romanian aircraft enthusiasts that would not be able to tell the full name of the aircraft factories ICAR and S.E.T. , yet here you are, rendering their respective names in flawless Romanian…
As to the powerplant however, I must regretfully inform you that the aircraft pictured did not fly the IAR K7 (aka Gnome-Rhône 7K Titan Major) but the more advanced IAR K14-1000A, capable of almost 1025 HP, fractionally more than the Gnome-Rhône 14K Mistal Major upon which it was based.
