Charles Peterson's System evolved through a series of patents over the course of the 1890s. By the end of the decade and the start of a new century, its essential components were well defined: a cooling chamber in the mortise for collecting excess moisture from the smoke, a graduated bore in the stem, and a P-Lip mouthpiece. The System has stood the test of time, delivering generations of pipe smokers cool, dry, and flavorful smokes.
Today Peterson System Standards are available in thirteen iconic shapes. They are available in smooth finishes and feature a nickel band. 9 mm filter
