The plainest English double that I have personally seen or shot was a C&H (see photo), but they also made or sold some nicer doubles as well. As Marrakai says, you can't catagorize all Coggies the same.

People tend to put Rhoddas in the same catagory, but I have a plain grade Rhodda, and I prefer it to the C&H. Other people may disagree
