An12 Crew.
When I flew with Antonov on the 12s:
Captain Normal left hand seat.
First Officer right hand seat.
Navigator in the nose .
Flight Engineer on the seat between the pilots.
Radio Operator behind and lower than First officer.
There was another seat behind and lower than the Captain.
The rest of us were in the area behind the flight deck.
I never flew on other company's 12s so can only tell you what our layout was. The aeroplane, to many looked strange with the anhedral on the wings, but have you ever watched a duck come into land? Nice to fly on and not too noisy.
The cargo compartment was unpressurised, so all the crew, both operating and loading/technical crew were accomodated in the pressurised capsule at the front.
Hope this helps.
