Construction Numbers of I-16s?

[Dénes Bernád]

Is there a way to check the validity of the Construction Number of a particular I-16?

I have a photo of a belly landed I-16, photographed probably in the late Summer of 1941, with the c/n stencilled in white over the rear fuselage, the fin and the rudder. Also, a white, diamond shape logo is applied on the rudder top, which I assume is the constructor's logo. Unfortunately, no individual number was painted on the airframe.

The c/n appears to be 5210935. Would it be possible to find out the details of this particular 'Ishak'?

Thanks,

Hello,

Yes, this I-16 was built by Factory No 21 in Gor'ky. It is an I-16 Type 5 (M-25A engine). 521 = Type 5, Factory No 21, and 0935 = aircraft number. I believe that it was built around 1936.

does the photo show a reflector gun-sight or a telescopic gun-sight?
is the canopy the forward-sliding version or the fixed type?

if this has a fixed canopy and reflector gun-sight then it was produced in 1938
although I am not 100% sure I think it is plane 35 in series 09 , indicating
late production.

also, what is this diamond-shaped logo ?
I've never seen anything like that on an I-16.

Here is a scan of the photo and a detail view of the diamond shape logo on the rudder top.

I am still mystified at the logo.
could it be a factory logo? or quality-control ?

the rails for the sliding canopy can be seen but this plane has a fixed windscreen. (with unpainted framing)

although the telescopic gun-sight is not visible it appears that the forward mount(s?) have been modified with a ring sight. this is consistent with the reflector gun-sight.

I'll have to examine the photo a little more to be sure of the exact colors used. (if you are interested)

I would assume it's a factory logo, but it would be nice if someone could confirm it.

As for the other details you mentioned, it would be nice if you could share your thoughts with us.

Thanks,
