There are pics in my barn if you care to look. She's a B/W Tobiano just like the mare in your video. If you want to do a search for her on allbreedpedigree.com her registered name is Mi-IMABLACKDIAMOND.
She currently stands around 15 hands (I haven't measured her) but she's going through another growth spurt as she's butt high. If you think you might be interested I can always take more photos when I'm back at the barn tomorrow.
