I have found this. I am led to believe it is a pipe tamper but thats about all I know. Could anyone give any more information about it please.

"It is not enough to fill a pipe and put it to the mouth and set fire to it, for even the country bumpkin knows as much. It is only correct to hold it with the left hand, have the right hand provided with the stopper, impress the onlookers with majestic mien, sit in the proper attitude on the chair, and finally, to take enough time for each pipe and not treat with hasty irreverence this heavenly food."
-Peter Burmann on pipe etiquette, c. 1710
