Slave Shackles

I am researching this for a friend who purchased these shackles at a local garage sale. The last owner recently passed away and his family decided they did not want them anymore. The grandfather of the last owner was the one who acquired it, no one knows where from.

My friend has been told they are american slavery shackles, and my research has confirmed this. They are clearly handworked with no signs of welding or other machine work.

Here are some links to pictures of the item:
