Dunno, link takes me to a page with many pics and when I try to increase the size it wants me to login. Sorry.
If it's the pic in the upper left, it kind of looks like a floor jack handle.
It could also be a manual handle for a slide motor but I don't think that's it.
You can place pics directly in your post.
