Your French translation is correct, Raimey. Per the author of that bit of text, it'd have to be a post-1930 gun.

Re the intertwined VC, that is a V-C trademark. It's shown on the first page of their 1922 catalog, albeit in a circle rather than exactly as it appears on the flats of that gun. Assume it stands for Verney-Carron. One of several trademarks they show on that page, the others being: VERCAR, Colonial (in script), Helice Grip, and HelicoBloc. All listed as registered trademarks.
