Can anyone ID these things

[kimonswanson643]

Found all at a civil war fort. The bullet casing has no writing on bottom so I don't know any ideas on the age? The circle thing I just don't know? The four leged stand I don't know? And the hook looks broken off of something? They all are iron except for bullet case. Please help me wit IDing them as civil war or not. Thank you.

A caliper would help you determine the size of the round. The 4 wire item could be a simple camp stove. Sit a pan on top of it & make a small fire under it.

The cartridge casing could be from a Spencer or Henry rifle, the round item looks like a ring, the 4 wire item I agree with CaptEsteban and the hook thingy I have no idea

Last thing is an Alien Space Particle, you could probably sell it on ebay for some big bucks. it's in good shape. Good finds!
