The discs are numbered. No hallmark found and unidentified. Nice weight.

Wear on the finish along the outer edges of the discs. 

Other minor signs of use and wear throughout.

There are a few small connecting links missing between the discs so it has previously been threaded. Will need to be threaded through all discs or ideally have the smaller links replaced. It can also be worn as-is.
