I own a K & P Peterson Standard 312 or 512. I can't make out if it is stamped 312 or 512. I love the shape (full-bent, I am a great Sherlock Holmes fan-original Basil Rathbone Series) and it is not a bad smoke. However, I do not like the P-Lip (hole on top of the stem design). Also, this is a "SYSTEM-PIPE" and it requires a pipe cleaner to soak up the extreme moisture the "system" captures. As such, it is rarely smoked because the "system" simply does not work for me and I am not a "wet-smoker". Still, I value the pipe in my collection. Perhaps, Peterson has other non-system pipes. But, I just have not wanted to try another one to this day. I have owned this pipe for 15 years.
