What breed of horse is 14 hands tall?

Although technically a horse is a pony until he reaches the height of 14.2HH there are many breeds that stand 14HH. The large pony breeds such as Ireland's Connomara, Welsh, Cob, ect. can actually be registered as a purebred yet grow to horse size. But many of the foundation Quarter Horses were very small compared to what they are today.*

*It is not uncommon for a registered QH to stand 17HH or more.
