Please help with Salir etched crystal perfume bottle

I have an etched crystal perfume bottle I was hoping to get some clarification on. It is signed salir in script. I am guessing it dates somewhere in the 20's or 30's. The majority of pieces I have seen with this signature have been associated with Buccelati, the Italian silversmith. I am trying to find out if it was the group S.A.L.I.R. that produced these pieces for them or if there was someone with the name of Salir. The crystal is very thin. Any help would be greatly appreciated.

I have asked an expert to take a look. Stay tuned!

Any ideas?

The only mark I have on file for S.A.L.I.R. is the marking with the period between each letter used by that company, as far as I've been able to determine they did not use a SALIR mark without the periods. I've seen a few pieces with the plain SALIR marking, but they all are much lighter and thinner glass than the S.A.L.I.R. examples, the engraving is somewhat different as well and they appear similar in style to pieces made in Czechoslovakia rather than Italy.
