A few years ago I got a Wiltshire ram from Jean Burke, she has a very high quality flock (Ventonglidder Farm, Ladock, Truro, Cornwall. TR2 4QE jeannieburke@btinternet.com 01726 882201/07769 706975 ) and is very active in the Wiltshire Horn society. Have a look at the society website.
We are now keep Shetlands as they are smaller, but the Wiltshires produced a good meat lamb on minimal additional feed.
