Per the 1922 V-C catalog (several years after the invention and patent of the Helice system by V-C), the only two copyrighted names they were using that included some form of "Helice" were: "Helice Grip" and "HelicoBloc". However, other forms of "Helice" were later used by V-C. For example, I owned a V-C 16ga with "Helice 33" on the top lever (the 33 indicating the year of the gun's introduction). That was apparently the first V-C double on which the traditional flat leaf springs were replaced with "rust-resistant" coil springs. That according to the pages from the contemporary catalog I received from V-C when I inquired about my Helice 33.
