This is a deep conical bowl which should make packing flakes easier. A dark-stained rustication surrounds the bowl and the square shank. The maker carried the square shape through the taper of the black stem. With the flat bottom of the square shank, the pipe sits on its own. Likely made after 1990 because the stamp reads, "Jermyn Street."
