I have a silver filigree bracelet and I am curious of the markings on it, I presume it's contenental. I have acid tested on the clasp, tag and edgeside of the panels and acid instantly reacted very strongly and appears not plated.




The marks are on the endside tag. I thought initally that the mark was 975 but looking again it looks more like an 9 / S than 975, I can see it's certainly not a 925 mark at any rate. I also know these contenental filigree pieces are typically .800 silver so seems odd to be .975.
There is then a symbol before the numbers which looks like an upsidedown anchor kinda thing ⫛
There is another mark on the tag (last image) which I can't make out at all, at a guess it may say SIL but I'm far from being able to read any of it.
Thanks a lot for any help with information that anyone can provide!
