I think I remember seeing chain like that as belts women would wear as an ornamentation on dress's also have seen it on purses it would have had a silver or gold tone to it before being weathered.
I found this one a while back. The other day there was a link TheCannonballGuy posted. It was a J M Eilers & Co Cincinati Ohio Saddlery Catalog. An exact match to mine was on page 148.
Search TNet catalogueno200jmei.pdf and you should find it.
