Always thought of a Rhodesian as having the wide, squat bowl, while the Bulldog as being the narrow bowl, resembling the shape of a bulldogs head. I have read and heard almost as many discussions on the subject as I have the English versus Balkan question. Honestly, I think the original distinction is lost in the mists of time. Besides, I detest unnecessary rules. In my book, your pipe is a Rhodesian. Enjoy!
