Peterson Deluxe System 12 1/2, P-Lip

• Not yet measured on this example: length, bowl height, chamber depth, chamber diameter, bowl width, weight. Measurements are added to the record as examples are re-handled.
• The attribute checklist is open on: topped. These are facts, not opinions — anyone holding this pipe can close them.
• Stem material is still open on this example. Vulcanite and acrylic age differently, and it is the first thing collectors ask — if you own this model, tell us what yours carries.
• The stampings and attribution here are as reported with the piece. A second, independent source — a catalogue page, a dated advertisement, a hallmarked sibling — is what would raise this record.

Nobody leaves empty-handed. If you hold the catalogue page, the dated advertisement, or a hallmarked sibling that closes one of these — or simply own this model and can measure yours — send it in. Contributions are checked, credited to you by name, and the record is updated with the date it changed.
