Agreeing on tiger claw wannabe for this sort of thing: https://www.google.com/search?sxsrf...mAhVwplkKHTmxDnMQsAR6BAgJEAE&biw=1600&bih=764 Can't see well enough to attempt a call on ivory or not, but originals souvenirs of Indian big game hunting, so maybe. Marks on pre-made parts like jump rings may or may not speak for metal used elsewhere.
I took it outside in the sunlight with a magnifying glass & I can't make out first part but last part in a sharper/different stamp/mark says MAY 1911? Is that a possibility on the small ring between chain & claw?
