Don’t be stumped Kiwimac…to let the forum progress I’ll give you a big help…
there is another polish manufacturer called Podlaska Wytwòrnia Samolotòw (PWS), so…
carson1934
oh!
So that’s the reason why the tail structure looked for me familiar with PWs-33 Wyzel! 
TGR
PWS-19 reconnaissance-bomber high-wing monoplane, 1931 (meanwhile the PZL.23 Karaś had been developed by PZL and as a result, works upon the PWS-19 stopped.)
Well, I’m glad we worked it out. 
Yes I’m glad too. This challenge proved to be more difficult than I thought.However you must admit that I gave you very substantial help.
Well let’s wait now for Tiger’s offer…

Dear Gentlemen!
Let you identify this bird!
I have removed all markings and codes, but I still feel this is an easy enigma…
TGR
Caproni Ap.1, I think (at least I hope so : ) ) .
Well done, Sir!
Caproni A.P.1 - exactly!
"Designed to serve both as a fighter and an attack aircraft, it was a low-wing monoplane with a fixed, trousered (spatted) undercarriage, of mixed construction. Although it was a monoplane at a time when many of the air forces of the world were flying biplanes, the Caproni was still an anachronism with fixed landing gear. "
Congrat, it’s your turn now!
Dear Tiger
first of all my congrats to Kiwimac for guessing correctly the Caproni AP1 (I got in too late!..), secondly I wonder if you could re-send the image of said aircraft complete with markings and codes as I do not have in my files an inflight pic without spatted undercarriage.
Thanks in advance, we are now anxiously waiting for Kiwimac’s offer…
Carson1934
Ok, let’s try this one.
Dear Kiwimac
this is the Dobi III a production of the lithanian Dobkevicius of 1924. He also built Dobi I and Dobi II respectively in 1922 and 1923…
This was an unusual wing shape but it seems it worked satisfactorily
Cheers
Carson1934
Wonderful, over to you.
This is my next offer and I hope you like the pic as I did…
Carson1934
Is that the USS Akron / Los Angeles and a Consolidated N2Y-1?
Good morning Kiwimac (good evening for you)
I don’t know if the airship is USS Akron but the aircraft is not a Consolidated N2Y-1. It’s a similar but different manufacturer…
Cheers
Carson1934
Oh, the good old Vought UO-1 piloted by Chief Aviation Pilot J. O’Brien, and photographed while approaching the USS Los Angeles. Direct link is available here:

That docking trapeze indeed was a very distinctive element, my dear Mr. Carson. Thank you!
Oh dear Mr. Librarian welcome back!
It is indeed the Vought UO1 which evidently proved more difficult than I thought.
I’m expecting with glee your forthcoming offer
Carson1934
Thank you, my dear Mr. Carson. Unfortunately, our regular professional obligations sometimes are quite demanding, but that’s life…
Anyhow, here is my brand new offer for all our distinguished participants in this thread:
This machine is representing one infinitesimal unit of a grand could-have-been cluster of unexploited chances in aircraft industry, and this post is only a lonely tribute to that magnificent group of engineering daylight dreamers whose work never was appropriately compensated.
Well it doesn’t look very attractive…but the landscape looks italian…could it be a front view of the Piaggio P32/II or Piaggio P32/bis with in line I.F. Asso engines?
On the other hand if I’m barking the wrong tree could you give us a hint about its nationality?
Look forward hearing from you…
