Anyone know if the Russian K-7 SuperFortress was real (photos)

I have kept track of most aircraft that have ever been built then
yesterday I ran across this ?
I find it hard to believe it ever existed especially back in 1930

Please look at the photos below and tell me if you know if this is real
or faked and if real did it ever fly ?

I count between 18 and 20 engines on it (some are pushers)

Please send me an email at

With any information on this

Russian K-7 or Ka-7 SuperFortress ??
I have searched Russian K-7 Superfortress but found another Russian 6
engine bomber ?
