Here's the deal on this one - when I can't ID something it tends to just sit on the desk. This one's been kicking around long enough so time to go - this is what I know about it. It measures 7.75 inches long. The clasp is strong and secure. There is a logo on the clasp. See pic 4. It appears to be a D with like a lightening bolt running thru it. I have no clue who that is. Now what is it made of? Absolutley not clue. I do know it is not plated pot metal. It could be sterling but there is no stamping to indicate that. My best guess is stainless. It's very nicely made and shows no wear. The links are very fluid / flexible. And that's what I know about this one. Your buying this as is - as you see it.
