Sutliffe 507-C folded and stuffed in the Barontini 1/2 spigot bent billiard with 9mm charcoal filter and acrylic stem. This pipe, which originally would get too hot to hold because it had 50-70 pinholes in the straight grain briar, having been wood filled, sanded and refinished, has now become one of my favorite and best smoking pipes. It looks a little like a Ser Jacopo Delecta to me. Now a great pipe. It is also finally developing cake in the bowl on top of the pipe mud lining. It may not be much to another, but I am very pleased with my efforts.
