Thanks. As I know little of Peterson Pipes, it seemed a good idea to ask Chuck - our resident Peterson guy, about this Pipe. He thinks that it may be a 312. A faceted meer in the 312 shape is somewhat unusual My thought was that the bit might have been a replacement on this Pipe, but Chuck believes that it is likely appropriate to this Pete. It's good to have access to people that know a thing or two. The African Block Pipes can be good smokers, with a bit of care. I keep the cake trimmed down to the Block and clean them with Everclear and a shank brush with plenty of Pipe cleaners after a smoke. I also wax them. They are not as efficient as Turkish Block at heat dissipation and absorbency, but by keeping the Block surface available to do it's work, they are a good smoke. They absorb the Beeswax and color, which is an indication of their ability to absorb. Yes, they can be heavy - especially the calcined Block.
