The C1 “inherited” later Vulcan refinements, though, including the safety, a heavier 16mm barrel (better balance IMHO), and the curved trigger (did much to help the awful grip position).
You are indeed correct (but is it 14mm or 15mm? Must measure mine.).

I was using “Vulcan action” to mean the base improved Hawk design. The Vulcan was introduced (1979) a couple of years before the Victor (1981) or the C1 (1983). So in my mind, any later Vulcan-derived gun was a variant of the Vulcan, if that makes sense.
