Hello, I like to restore antique clay pipes, normally they are found broken as bowls and sections of stem the last photograph shows you what I usually start off with.  The rule of thumb, the smaller the bowl the older the pipe.

I restore by joining the bowls and stems using metal tube sections inserted into each alternate end of the stem section. The metal tube acts as a strong spine joint for each section joint of the stem and to the bowl, this makes the bore completely obstruction free. I also choose the stem sections that have the same bore size as the bowl, so the stems are generally the same age as the bowl. 

Once the joints are solid, I blend in the clay stem joints to match and this is how a pipe that has been lost over 220 years plus can be used ( to smoke from) or displayed. 

Here is one of the younger in age Tobacco clay pipes I have in stock from a batch of recently restored clay pipes.

The Pipe bowl shape chart dates the bowl to circa 1750 to 1800, Covering the reigns of King George 2nd to King George 3rd  

There is evidence of one maker`s initial letter (S) on one side of the heel, but the other side I cannot make out the other letter. 

Please see the Pipe history shape chart Figure 29 for bowl comparison

This pipe has a clear bore so you can use this to smoke from it .I shall supply with this pipe a copper cleaning rod to help clear the bore if you choose to smoke from the pipe. 

I found a photo of an old painting with gentleman having a smoke from similar pipe
