Well, I'm old enough that I don't even remember most of what I read, though I do know it included most of the Black Stallion series (and lots of "girl wants horse, girl meets horse, girl loses horse, obstacles overcome, girl gets horse" rubbish).
But what I still have on my bookshelf back in my childhood bedroom (much as I left it 30ish years ago) is Will James! Looking him up, he really dates from my mom's childhood, but several of his books found their way to me. I barely remember them so I can't even say if they're any good, though one did win the Newbery Medal in 1927. I'll have to reread and see what I think . . .
Oh, and My Friend Flicka
and its sequels - Thunderhead
& Green Grass of Wyoming
ETA: Oh, of course, I forgot Marguerite Henry until I reviewed the posts and saw someone else mentioning her! I have several of the Breyer boxed sets (book + model) - Misty, Brighty, Justin Morgan.
