Cobs are a type and not a breed (though efforts are currently being made to establish various stud books). It is becoming extremely hard to find good ones, which should have a leg at each corner, plenty of bone (9 inches or so), a stocky build, with comparatively short legs, 15.1 hh or less but still with some refinement and quality. Temperament is also a very important part of their type because they should be a comfortable ride, with excellent manners, a horse to take the Vicar or one’s Grandfather out hunting. The short stature was to make them easier to mount. The thick mane is trimmed off because they just look silly with plaits the size of tennis balls on top of their habitually chunky neck. The current market for sport horses means that the magic mix that produces a classic Cob isn’t happening very much now. Once seen, they become very recognizable. The British showing world introduced “maxi Cobs” a couple of decades ago because there are a lot of taller horses that can pass for a cob if the weight is piled on and the mane is taken off - but these are not the true Cob. My tech skills are limited right now but Google the Cob “Our Cashel Blue”, ridden by Alister Hood, as a good example of a lightweight. The horse hunted during the winter and showed in the summer.
The Welsh Cob, Section D of the Studbook, is most definitely a breed.
In the UK an AQH is an expensive beast, with a few extra thousand on the price tag because they are so exotic. Very few people ride Western.
Levi jeans and Carhartt are expensive, top range brands in Europe. Again, relative availability, but combined with effective marketing.
“Working Hunter” as a UK show class did actually develop from the American hunter model as a way to have fun in the summer but, given the different culture, the horses are expected to demonstrate that they really could have a day out hunting: function takes precedence over form. “Show hunters” is a beauty parade, though the horses are ridden by a “ride judge” for ride and manners as well as being assessed for their type and conformation by another judge. The two then confer to pick the winner.
