Radford's Seventy Six Shape 4 Smooth Straight Billiard, Vintage (Owner-Stated Era)

This reference example documents a Radford's pipe of the Seventy Six line, carrying the shape number 4 and executed as a smooth straight billiard fitted with a 9mm filter system. The piece entered the archive as an estate pipe sourced from France, per the owner's account, and it serves here as a study example of a filtered production billiard in the classical mould. The billiard is the most canonical of all pipe shapes and the yardstick against which pipe proportion is traditionally judged: a broadly cylindrical bowl set at or near a right angle to a shank of roughly equal length to the bowl's height, the whole terminating in a stem that continues the shank's line. A smooth finish, as seen here, leaves the surface polished rather than carved or blasted, presenting the material's natural figure. The 9mm filter bore is a construction detail with its own history — filter systems of this gauge became a hallmark of Continental European pipe making and smoking preference through the twentieth century, requiring a shank drilled to accept a replaceable filter cartridge seated between tenon and mortise. Within the Radford's catalogue, the Seventy Six designation identifies the line to which this pipe belongs, while the numeral 4 functions as the factory shape reference, a common convention among production houses for cataloguing their standard forms. The line name, shape number, and filter gauge together remain the most instructive identifying features of the example.
