No, that's not it. The top lever in your gun appears to push on a rod which protrudes from the breech face. That's not a design feature of a Helice or Helicobloc gun. The 1922 V-C catalog shows the design of the "Helice Grip" compared to the locking mechanism of an "ordinary triple bolt" system. The Helice Grip has 4 pieces while its competitor has 7. Basically a question of being simpler while also being sufficiently strong. After V-C's patent expired, many other French guns were made using the same design.
