A06450 is Pal's Prince, a 1997 dark bay gelding with white on left hind heel, higher on inside, double diagonal cowlick above eye level, higher on right. Ran entirely at Canterbury Park from June 00 through August 02 for breeder/owner Patrick Crawley.
My bad - the gelding has two socks behind, not one as I originally indicated. And he also has a very, very faint star (about 11 white hairs). New links in the OP include a shot of his face, and the whole horse. He also has distinctive black 'freckles' in his socks.
Thanks again for any assistance you can provide in deciphering this tattoo and this guy's identity.
He's a good boy, steady and willing, ridden by his young teen rider, and doted on by her daddy. (They're all so cute!)
Don't wrassle with a hog. You just get dirty, and the hog likes it.
Is this a possibility? That fourth number really does NOT look like a 7 though.
Left hind: coronet and part of pastern white, higher in back; dark spots on coronet. Right hind: coronet and part of pastern white, higher in back; dark spots on coronet. Double horizontal cowlick above eye level; median cowlick above eye level.
