Living History Farms @ Waukee,Iowa has have @ least 2 of the breeds you are asking about. They will sell or give away offspring. I don't think that they have Tamworths, but I may be wrong about that. Tamworth are a small framed up eared red hog that thrive in tough conditions. They are still used in outdoor farrowing operations here in Iowa. They do not have large #s as far as litter size is concerned, but survival rates are high. I have no personal experience with the other breeds and the only place that I have seen them, was @ Living History Farms. Brent
