The clue is in the rotor.. All Russian and most European designed helicopters have the rotor turning clockwise looking from the top. Americans have them turning anti-clockwise. The Super Frelon, even though it was designed by Sud Aviation in France uses the S64 transmission and rotor drive. I remember the first batch of them sitting at Marignan awaiting US govenment approval for their export.
The three view illustration looks pretty official, therefore should be correct, so the chances are that is is a development or redesign of the Z8.
Why do the rotors go different ways. The same reason why European piston engines propellers predominately turn clockwise viewed from the front, Americans, anti-clockwise.
All engines turn the same way (clockwise) but the Europeans left the engine in the normal position and mounted the propeller on the front of the crankshaft. The Americans, on the other hand mounted their propeller on the power take off position on the rear of the crankshaft in the same way as clutches and gearboxes. The result is that the engine it is mounted back-to-front in European eyes and the propellor goes the wrong way.
When the first helicopters were designed their rotors went, naturally, the same way as their predecessors propellers.
