Vintage Finnish design rare order bronze bracelet with safety chain

order 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, 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.
