Antique or Vintage Statement Festoon Necklace. Silvertoned Alloy with Roosters

VERY cool necklace purchased in Butte MT - measures 18 1/4" long and each link is slightly under 1 1/2" tall.
It looks European to me, but there are no markings.
This is a substantial piece of jewelry.
If you have any questions, please let me know and I'll try to help.
Thanks for looking, and happy eBaying!
