I dug up this humble piece of clay pipe stem in the garden the other day. These are a not infrequent find heareabouts and I just used to toss them aside as of no interest, because I'd always assumed you need the bowl shape to identify the period in which it was made. Turns out I was wrong: the thickness of the stem/shank and the diameter of the air hole gives you an approximate guide to within just a few decades. This one is 6/64ths of an inch, which gives it a 72% probability of being in the date range 1680-1710.
The method is accurate on both sides of the Pond. Thought it might be of interest to some.
