unidentified turks

My last amendment crossed with John’s posting. I reckon he’s cracked it.

Can anyone identify these two aircraft demonstrated to the turkish army in the late twenties or early thirties?

It is a Letov, a variant of the S31, probably the S’131 which was demonstrated throughout the Balkan states and probably Turkey. I go with JDK that the second a/c is a Potez 29 (developed from the 25).

Are you sure it’s a roundel? To me the aeroplane in the first photo seems to have the Czech civil register “OK” on the fuselage and on the bottom of the wing.

I still think it’s a roundel, although I’m quite open to being convinced otherwise and the letters on the fuselage could well be OK.
The braced horizontal tailplane set quite high on the fuselage and the fairly wide-chord cabane struts should be a help in identifying it. The wheels seem to be set well forward, which is what sent me off looking at later model SPADs.
There seems to be some sort of marking on the fin and rudder. Difficult to say if it’s a tricoloured flash or not, though.
I had at first thought the second plane was a monoplane of Fokker-type layout, but on closer inspection you can see an interplane strut far left, and come to think of it the elevated group on the right of the engine have to be sitting on something. Silly me.

(Change added later) Definitely not a Letov S19. Have a look at this:

Wrong interplane struts, slab-sided fuselage, wrong fin and rudder, etc etc

Look closely at the roundel under the wing of the biplane, and you can see that the outer ring appears darkest.

Nice detective work folks.

I’m with John on the Potez idea, but I think it’s a 29, or perhaps a 32. The 25 didn’t normally have that distinctive Potez ‘Vee’ windscreen.

Potez 29.4 from here:

I’m going for Letov (S19) I’ll have to check, and a Potez 25.

Looks like the second shot was taken in a Francophone hangar – No Smoking etc.

Look closely at the roundel under the wing of the biplane, and you can see that the outer ring appears darkest. As nearly all film then had blue-sensitive orthochromatic emulsions which endered reds un-naturally dark, this suggests to me that it is probably French as well as the monoplane.
Plenty of things it almost looks like. It did cross my mind for a moment it might be a Gloster Gamecock, but see above. Besides, the exhaust stubs and the fin and rudder outline are wrong for this.
It’s not a late model Bleriot/SPAD as these had single interplane struts. Hmmm….puzzled.

William

Unless someone nails it here, I suggest you ask at the AWF.

For what it’s worth, the second aircraft is, I think, French, but I can’t remember which manufacturer…
