Hey Pat,
I'm really not that sure as to whether or not there's any kind of relation between the two firms, but my take on it would be that they're cousins, much like the renowned Spanish Caballer companies.
As for the "S.A.S", I'm not entirely positive in what it stands for, nor do I know what "S.R.L" spells out to be (something in Italian, I'm sure), though I only noticed the "S.A.S" appearing at the end of "Panzera" in recent years.
Trav.
