Watch chain full of 12 teeth? or what please?I thought that so many claws and teeth were used with turquoise... maybe?

I hope some member may have seen this before. I am not familiar with this shape tooth. The rings I have tested, 14k gf. The hook and toggle are 14k. Any ideas to identify or where to look for similar teeth… I do think they are teeth. Thanks!

What are the letters on the end piece of the chain, the eye. I have looked at more teeth than I care to and have not found a tooth that looks similar. Maybe those initials will help us.

Sorry to have taken so long to get back with you and show the photos. So fascinating! I am grateful for any further information. MEW.
