The importer's name was required, I believe, after the 1968 Gun Control Act. However, a lot of importers stamped their guns even before that.

Your gun is a true sidelock, and one of the top end models. All V. Bernardelli guns are pretty darned good, but the majority of them we see in this country are sideplated boxlocks from their "Roma" series.

I don't think all Bernardelli safeties were marked "sicura". Can't say for sure, but I think that some destined for this country were marked "safe".
