what is it 3

This may be some type of old wagon component. I found this in an old pile of iron near a Fort. I think the Smithy had this stuff hauled away and dumped near the top of a hill. There were hundreds of pieces of iron everywhere, including dozens of old horse shoes with square tacks.

Could this be part of the cot? They look like the same rivets with holes spaced the same. http://forum.treasurenet.com/index.php/topic,449925.0.html
