Could someone help me identify the things I have circled in the picture. They were found in the field beside my house, if that helps any.

Almost looks like old gate hardware, just my 2 cents worth.

Looks like you've got a hoof pick, a couple of hinge straps, and a gate latch!!

I thought of farming related items and by the looks of them they've been there awhile.
