At one point in my pig life, I was considering mating my Saddleback sow with a Hampshire boar and had no problem finding quite a few contenders nearby, though there are more in the north and Scotland, way too far for me on the south coast. Think they are relatively rare as they are not really a British breed at all - they were all imported from the USA, but they do have a society here and do shows and that sort of thing. Apparently they produce a leaner carcass than a Saddleback, but perhaps the Brits just prefer our traditional, lop eared Saddlebacks instead, and which you can make lean with a well controlled diet.
