Reproduction Chaika 2

I've bought an interesting Chaika 2 camera with a seller telling me it's an early version of the camera because of the special lens.

But today on a Russian collectors group another fellow collector has posted his set which includes this exact camera in it:

So it seems like this a reproduction model (at least the lens) and the scale on it is 1,2,3 instead of distance in meters which corresponds to the markings on the copy table. Mystery solved! [:)].

Great!
I also own this lens, and I was also puzzled about its origine.
Thanks for the information!
