| All pipe fragments
recovered from the shipwreck thought to be Queen Anne's Revenge
appear to be of English origin based on observable manufacturing
traits. No fragments exhibit a maker's mark of any type. Therefore
dating of these pipes fragments was based on two observations (bowl
shape and bore diameter) and calculated in three ways to assess
a chronological dimension to the assemblage. Based on bowl shape
using Oswald's observations (as seen in Noel Hume's 1969 text),
three pipes date to the general period of 1690 to 1750 in manufacture,
while one appears to date earlier to the 1680 to 1710 period. Using
Harrington's observation of bore diameter changes from 17th to 18th
century (generally bore diameters became proportionately smaller
- narrower - as the stem grew longer) which are subdivided into
five distinct categories of diameter (ranging from 9/64th of an
inch to 4/64 of and inch as the latest), the nine measurable stem
fragments fall into the 1680 to the 1710 period of manufacture.
