Iron items. Can you help ID any?

[HuntingRelics]

These items were found within Civil War relics, however I've also found early 1900's farm items in the area. The horseshoe is much smaller than most I have found.

Your "horse shoe" is a Mule Shoe.,

Top left looks like a trigger guard to me, does it have any holes in it for screws?

Not a mule shoe.

The horseshoe thing looks some kinda hinge device?

I'll have to clean some of the rust off to see if it's a trigger guard. Thanks for the insight everyone.

Your piece with the ring in the bottom right is half of a Bit.

and I still feel that the shoe is from a Mule.
Second row from the bottom, first on the left
A bit more cleaning my show the nail holes.

The toggle chain might be the end for a cow chain They would place the end through a hole in the stall while they milked the cow . The u shaped item looks like some type of clevis to me but I am not positive
