Yep, twisted wire--make it into a tp roll ring?
2nd is a sweet iron, loose ring snaffle.
3rd is the "bit" from the set of "Bit and Bridoon." That means a 2 bit bridle, often used in Dressage. It is the snaffle and you also stuck a curb bit in the horse's mouth, too, hence the skinny mouthpiece.
They are ALL old bits. I bought one that was in a box at auction many years ago.
