They are not the same. Rizzini's look like every other ugly Brescia built O/U out there, while the Inverness looks like a sleek Mckay Brown. Mechanically, they are very similar, but why should that surprise anyone? They are guns, and people have been copying good gun designs since gun design began. The Winchester M-70 is a copy of the German Mauser, yet we say the M-70 is as American as apple pie. Win Hester wasn't the only company to copy the design ejther... The Inverness name was owned by CSMC, not Rizzini. The name Inverness was slapped on a Rizzini gun and imported into the US. That's why there was confusion when CSMC began making their own Inverness, and why many people believed CSMC was using Rizzini actions, which they weren't.
