Vintage Finnish design rare bronze bracelet with safety chain retailer

I don't know the name for this design, or the designer.

There are beast heads, maybe leopards, showing their teeth.
Ten heads.

This bracelet is about 18 cm long, retailer and it has a safety chain.
Box clasp fastening.

This bracelet is very old, my own estimate is it's from the 60's.
It's hallmark says only "Finland".

Used condition, some wears inside.

Very collectible.
