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 300 years can be used ( to smoke from) or displayed. 

Here is the Longest Tobacco clay pipe I have in stock from a batch of recently restored clay pipes.

The Pipe bowl shape chart dates the bowl to circa 1650 to 1680, so the time period of Oliver Cromwell to the restored monarchy of King Charles II 

You may of seen the old paintings of a gentleman sat in his chair holding extremely long tobacco pipe or a yard of clay pipe 36 inches or 90cm.  This pipe is small compared at 35.5 cm long.

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 old painting with gentleman having a smoke from similar pipe
