The registration papers alone don’t mean much, you need a transfer report from the last owner of record, the one listed on the registration paper as the owner.
With both of them, you can register him in your name.
If you don’t have a properly signed transfer report, that determines that is the right horse as per the seller, you need to contact the AQHA and they will send a notice to the last owner of record and see what they answer.
If that last recorded owner is nice, they will send the signed forms and the AQHA will proceed with getting the horse in your name.
Googling his name, this is what I got, his pedigree and some videos:

Looks like he was shown some in western pleasure, reining, barrel racing and pole bending in 2007?
