I have but 1, a 1970's Peterson Dublin and London. The chubby Rhodesian is 1 of my favorite shapes but am about ready to relegate mine to the back racks simply because it has an incredibly shallow bowl. I can get about 30 seconds of smoking out of it before I have to re-fill. So, is it common for the bullmoose to have shallow bowls? Was it common for Peterson's to be so shallow?
