This is a fine dore chandelier, made in the French Empire style. You would be best to have the wiring repaired as opposed to buying a new fixture.
Is there evidence on this hanging light fixture that it was once converted from gas to electric? As well, is there evidence of small holes for attaching the crystals that you do not have?
I am going to opt-out here and open your question again to all the experts at no additional charge to you in hopes that you can get some second opinions. The style, and outside wiring do lead me to believe that this was converted from gas. I have not found a match to the SAV initials.
