Any ideas on this one?

[ANGRE7]

Dug this Yesterday, thought it was junk and was about to chuck it when i noticed the shield indentation...re ckecked the hole and pulled out the tiny chain aswell. Might do some electrolysis on it and workout what its made of, but thinking copper at this point.

Any Ideas!?
