Whoops, your pics didn't show up! I can help if you can try posting another link to the picture!
If she is 7" tall then she's a Classic mold. Here's the site I use to identify Classic Breyers:

Try to ignore the colors, and just look for Fox's posture/shape/gait etc. Most molds get issued in a lot of different coat colors. Click through to see all the colors and find her listed!
My friend has that breyer, and yes she is a Classic. She (or he; not sure which :D) is a Throughbred, and comes with the "Veterinary Care Gift Set" according to the Breyer website. Here's a link (keep scrolling down, it's there)

Hope this helped!
Did it come from the vet kit? I thought it was a WalMart mustang. (I don't do Classics) The mold is Duchess, Black Beauty's dam.
I'm not sure what breed it is but you could probably find it in the 5th edition of Breyer Horses Collector's Guide which you should be able to get from your library. I hope this helps. Good day!
