Those pictures are dark, and you can't see his red front end very well, it looks gray in those pictures, so here's a close up front: ('scuse the muddy bits, he's kind of a pig) Likewise I don't have a good picture of his striping on his hind legs, they don't show up well in the above pictures and you can't see them in his winter coat.
And he definitely threw his weird colors before he was gelded. Here's a few pics of his last colt, out of a gray perch mare:
At a month
And now, same colt, coming 2 years
So what would Claymore be, technically?
