Looking to identify a brand in Paragould, Arkansas

I've come in to possession of an App mare. with a cold (?) brand on her left rear leg. It looks like an upside down horseshoe surrounding a backward j. The horse is supposed to be registered under the name Cheyenne. I'm simply trying to verify the horse's age and any training she may've had.
If you have information about this brand please text Doug @ 870 340 xxxx.
