Large ornate antique candelabra - 9 arm

This piece is a real mystery to our family. We know it came to the US with my grandmother from Glamis, Scotland in 1920. There were originally two, but nobody in the family knows what happened to the other one. I inherited this from my mother's estate. This is a huge piece - 27" tall and 17" wide. It weighs 10 pounds. Now for the mystery part...there isn't a single mark anywhere - no hallmarks, no maker's mark. It is surprisingly light for its size. I don't believe it is sterling. It breaks down into two pieces. I have had this appraised more than 5 times, and not one appraiser could tell me where it came from or how old it is. There are three main themes - lions, snakes and soldiers with helmets. My daughter noted that the lions look just like the lions on the Scottish flag. Does anyone know what this is and/or its value?
