Odd hallmark on silver pendant help Identifying please

Hello, I’m new to the site here and just looking around for a little I have learned a lot already. I’m hoping someone could help me identify a hallmark on a silver pendant. The Pendant almost appears to be hand made as I see a little solder at connection points. It’s not marked 925 or sterling, but I tested the piece and it appear to be silver. Also it has a weird hallmark on the back and the same hallmark on the loop where you would put a necklace, you can see the hallmark in the middle of the picture I attatched. If any one could help me or point me in the right direction I would appreciate it.

By the way I don’t know if this is a British mark or from what country , but I didn’t know where else to post it.
