I was walking around trying to figure out what shape this was. It's a Peterson sub-brand, but has a shape that is recognizable. Well, after Pam let me borrow her shape chart, I can see that this is an XL-14. Can't exactly figure out why it's a second, though. Sure, there are some fills, but Peterson has fills on many of their pipes. The shape is really great, and natural patina has taken over - in a good way.
