Link bracelet

Apologies if you have seen this bracelet on the ‘Finds’ thread but as it’s just surprisingly tested as silver I thought it deserved a bit more attention.
I nearly didn’t buy it as I thought I could see copper coming through but it was very cheap so home it came.
Can’t find a mark anywhere on it except the clasp. It’s slightly damaged missing a ball (behave) but otherwise good. The tongue of the clasp is marked 7 and does not test as silver but all the other bits do.
Does anyone recognise the style or want to take a crack at if it’s very modern or a bit older. It feels like it has a bit of age to it but not very.
Possibly low quality foreign silver?.
Tarnish ( that wasn’t copper showing through after all) came off with a bit of silver foam and it’s shined up quite nicely.
Thankyou

 

Anyone?
