Ok:). I completely understand your wanting to know something if your horse’s ancestry. He is a handsome fella — I happen to have a just turned 25 registered Tennessee Walker that is built very similar to your fella. While I agree with the poster who said possibly some Saddlebred in there, one thing I know is that is not the chest of a Quarter Horse – not even a “running” Quarter Horse as we used to call the old Poco Line:)
Also, your fella’s neck is set too straight to be a Quarter Horse type:)
when hen you say a “–big head swing–”. Does that mean side-to-side or up/down. side-to-side movement means the horse could do a rack, stepping pace or the shake-the-crowns-off-your-teeth hard lateral pace. Your fella did not look like an off-balance washing machine in your video so I suspect hard lateral pace can be ruled out:)
Up/down head nod is synonymous with the running walk, which he didn’t seem to naturally gravitate to but again, a video of him walking no doing an intermediate gait would be great:)
Here are a couple of pics of my registered Walker that I took this year, around his 25th birthday. He has been with me since he was 2-1/2. They are taken at a similar angle to your 4th pic that doesn’t have a rider. Notice the similarities in the hip bone structure back they the rump. Your horse is a,so naturally high headed which my Rusty is, and that comes from his blood line:)
He is of the Prides Generator bloodline on his top side and his bottom side grand (or great grand, I forget) is Ebony’s Masterpiece. The absolute best compilation of Walking Horse history in the Net is Walkers West, if you care to look either if these stallions up:)

If my pics won’t load in this post, I’ll put them in another post:). Don’t get excited, I may be way off base but I see similarities between the two horses. Plus it’s possible your handsome fella has a couple of breed DNA’s in him:).
I offer this because I have always had an interest in who my horses are. BUT when I was first able to afford a registered horse. I NEVER looked at the papers until after I decided I wanted the horse. I am a lifetime trail rider so my horses were always bought on their heart and work ethic, not what was on the papers. The papers were just a means to better understand the horse and to feed the curiousity of my research-inclined mind:)
