Word of advice... IF you and your daughter do decide to keep and show him... work him with the nose lead every day up to the fair. The show itself should be the only time your daughter doesn't use it. It's so easy for us to "test" the animal to see if they're OK with using a regular halter, or riding the horse in a milder bit, or taking the dog's ecollar off, but it's also so easy for the animal to figure out when they're wearing the equipment that means "behave", and when they're wearing the "show stuff." Especially in this case, you do not need him figuring out that sometimes he has the nose lead and has to obey... and sometimes he doesn't.
