My 3 euro vintage linked bracelet with filigreen 4-cloves leafs. Help wantet!

I bought this bracelet at a charityshop in Stockholm for 32 swedish crowns, (3 euro). Its more goldy than photo shows. It has many small filigree 4-cloves leafs and a safetychain.
Last picture shows the hallmarks I can see . I understand nothing from this..Can anyone make something out of this? Where do this bracelet come from? Is it old?
What material is it mad of? Is it worth anything? I love this bracelet and often wear it, hope all the 4-cloves leafs will give me som luck!

Tankyou,
Maaaary
