Jeantet, as company, has a very long and distinguished family, the name first mentioned as early as 1775. By the early 19th century, the Jeantets had begun making their way into the world of pipes, starting out operating a turnery which produced wooden shapes and some wild cherry wood pipes. By the middle of the century, the enterprise blossomed into a corporation, with numerous workshops cropping up all over the city of Saint-Claude, eventually producing briar pipes in 1851.
The likelihood that this piece was created then is very low, though Eric guessed it to be from about mid-20th century due its figural shaping and the fact that the condition is still so good. But regardless, your getting a charming piece of history, made by a company that helped forge Chapuis-Comoy and Chacom.
