Some additional clues, my dear Mr. Carson? No problem – here they are! This versatile airplane possessed the lower wing somewhat behind the upper wing, and therefore we can say that the plane possessed a positive stagger, as well as an air cooled seven-cylinder radial engine. 
Dear Librarian
in spite of your latest clue I’m still unable, much to my shame, to identify a/c of your thread n. 678 of Oct.31
Now if you don’t want me to succumb under the unbearable burden of my disgraceful condition I strongly suggest you should provide one more clue or give us outright the solution of this riddle for the sake of the continuance of this valuable forum.
As somebody said:“Spes Ultima Dea…”
Or using the words of Foscolo, whom you undoubtedly know: “Anche la speme, ultima dea, fugge i sepolcri…”
with my deepest consideration

Grata superveniet quae non sperabitur hora, My dear Mr. Carson!
Here is another clue for you; at least one example of this handy little aircraft with the 150 HP petrol engine was captured by the Red Army and used for search and rescue work in the USSR after the war! 
Dear Librarian
“per fas et nefas” I tried to reconcile my meagre knowledge of utility aircrafts with the leads that you were kind enough to give me.
However I was unable to locate your aircraft and I feel it is now high time to hoist white flag and to let this forum go ahead.
However I’m sure that I’ll bite my fists when the name of this a/c is disclosed
Cheers
carson
Tollenti onus auxiliare, deponenti nequaquam, my dear Mr. Carson. Please, don’t worry - after all this is only a game.
And the answer is: Tachikawa KKY-2
All relevant informations about this almost completely forgotten machine are available here:

And now, without delay here is another one:
We shall be very glad to receive your kind offers.
In the meantime, as always – all the best!
Thanks very much my dear Mr. Librarian
That particular Tachikawa model was completely unknown to me…
“Ludus animo debet aliquando dari, ad cogitandum melior ut
redeat tibi”
Concerning the new offer this is very similar to the polish PZL P/38 “Wilk” but there is something that baffles me therefore I’ll keep on searching unless of course you confirm my supposition…
all the best to you
carson
Sorry please disregard my previous message it is definitely a PWS33 “Wyzel” of 1938 built by Podlaska Witwornia Samolotow of which only two prototypes were produced
Nullius boni sine socio iucunda possessio, my dear Mr. Carson!
Yes, you are absolutely right. My sincerest congratulations! And now, please – lead the way! 
Good evening dear Mr.Librarian
may I for a change offer you the following racer of the thirties now completely forgotten though a product of a famous manufacturer
Good luck:mrgreen:
carson
First glance I thought it might be a PZL P-1 but undercarriage is not quite right.
No kiwimac it isn’t from eastern Europe
carson
hmmm, Back to the books.
Dear Kiwimac,
since this aircraft seems to give you a hard time may I suggest that you should follow the lead constituted by the serial (registration) number fairly well visible on the fuselage?
Cheers
carson
In addition, my dear Mr. Kiwimac, one more highly useful clue will be the Italian sentence “Monoplano monomotore da addestramento.”
I did not notice the sentence in Italian. Is it in the photo or are you just giving me a broad hint? I had also searched on the registration but perhaps I was not accurate enough with it. Is it the Ambrosini SAI.2
Hi Kiwimac,
I’ll give you some important clues:
- it was built in 1928 designed by Ing.C.Pallavicino
- it won the first aerial tour of Italy (Premier tour aérien d’Italie) in 1930
- it had a variety of engines both radial and in-line
I’m sure the above will prove instrumental.
BTW it isn’t the Ambrosini SAI2
Cheers;)
carson
Ah yes. Your mystery aeroplane is none other than the Breda 15, designed in 1928 by Cesare Pallavicino.
http://www.flightglobal.com/airspace/photos/flighthistorical/breda-15-31979.aspx
It’s true I’d never seen this aircraft with this powerplant before, but the undercarriage and window arrangement are dead giveaways.
Later edit: Unfortunately, the mystery I had lined up is none other than the PWS33 “Wyzel” posted by Mr Librarian on page 46, ( A pity I missed it when it was first posted, it would have made for an easy identification) so It will take a bit until I can find another suitably obscure one…
Yes dear Wingsofwrath it is indeed the Breda 15 and exactly the Breda 15/S. What makes identification of this particular a/c pretty tricky is the fact that she was supplied with no less than four different types of engines, some of them radial and some of them in line therefore the nose of the aircraft differs rather substantially from one type to the other.
The ball is in your half therefore shoot!
Omnia vincit constantia
Cheers
carson
Allow me to kindly disagree on that, my dear Mr Carson - with the wealth of information you kindly provided us (nationality, name of designer, exact production date, engine power, in addition to the serial already visible in the photograph) identification by way of Google would have been a mere child’s play, even if I hadn’t been acquainted with the type.
In any case, I hope you will find this week’s enigma at least a bit interesting:
PS: I might be wrong, since I haven’t used my meagre knowledge of Latin since high school, but shouldn’t that be “Constantia vincit omnia”?
Yes my dear Wingsofwrath I admit I was a bit generous in supplying data for my previous mystery plane which I did to be quite honest to stir up the forum…anyway let’s now concentrate on your mystery plane which I for the time being do not know
Concerning the latin sentence you could obviously write “Constantia vincit omnia” which is however a bit of “latinus grossus”. May I remind you of the famous Virgil’s stanza “Omnia vincit amor”.
Cheers
carson
It looks japanese (Yokosuka family) a captured bird…am I off track?
My dear Mr Carson, I am at liberty to say that the aircraft pictured does not hail from the Land of the Rising Sun.
My knowledge of Latin are indeed sketchier than I imagined, and, at least in this case, were supplanted with knowledge derived from my own native tongue.
Since mine is language which, like other Romance languages, is primarily based upon the vernacular forms of Latin in terms of topic and grammar rules, it is only natural that I should find the literary form “unfamiliar”.
As far is Virgil is concerned however, I must confess that while I am acquainted with the latter’s work, I could never muster enough lexical prowess to read them in the original.
