I'm writing my bachelor's thesis about how the three distinct types of Quarter Horses diverged and what is the breeding goal for each type.

However, I barely find anything about the specific types. Most of the sources talk about the Quarter Horse in general, mentioning that the racing type is more heavily crossed with TB. I find very little material on halter and stock type breeding.

If anyone is a breeder or knows one, could you point me to the right direction? I understand that writing about a US breed from Europe is going to be more difficult, as I cannot visit stud farms. I'm mainly interested if there are any books or scientific articles regarding the types, but I'd be very happy if someone had stud horses and could help me out with conformation pictures and lineages :D Obviously, since it's a thesis for a degree, everything will be properly credited, including pictures and discussions.

I don't breed QH's but I've shown in the industry for years and owned QH's for years. Have you ever found the legends books by Western Horseman? They discuss a lot of breeding and influence type things.

I can try to help you. I am not a serious breeder or anything but I tend to stay relatively up-to-date on trends in the QH world. I can help show you the difference between western pleasure, rope, and english QHs if you want
