Emil Jardin, which I think was made by Thibouville.
Emil Jardin clarinets are some of the better French Stencils. And being made of hard rubber makes this a whole lot better than most plastic instruments. Hard rubber is prized for its dark tone. See the Professional Hard Rubber page.
Fixed October 2009, serial #1359B.
Top of LH joint: 14.8mm
Bottom of LH joint: 14.8mm
This test was done pushed all the way in. I would want a shorter barrel, and a standard 66 should work well.
This instrument is very appropriate for an adult coming back to playing, or intermediate players.
In fact, with a good barrel, advanced players would be happy with the way this plays.
