The name 'Zoli' has appeared on both O/U and SxS double rifles for several decades at least IIRC.

Of course, there was more than one maker with the sir-name Zoli in the gun-making business. The names Anatoli, Antonio, Andero, and Angelo spring to mind. Seems to be a fascination with names beginning with 'A', so it would seem that a particular A.Zoli gun may have been made by any one of a number of A.Zoli makers!

Here's a pic of a 9.3x74 SxS DR marketed during the eighties at least, called the 'Savana', and carrying Antonio Zoli's name on the barrels:
