Other clarinets were made stamped P. X. Laube, including a metal clarinet in three pieces. Both this and the metal one are marked “La Couture Boussey (Eure).” This seems to clearly be a Couesnon-made clarinet. All the marking is on the bell. So if the bell were lost, this would become a no-name clarinet.
I thank Roland J for letting me review this interesting clarinet.
Serial #23, marked twice in the LH joint and once at the top of the RH joint. There is a batch mark of 34D or D34 on the keyed joints.
Barrel: 63.9mm
Bore LH joint top: 14.4mm
Bore LH joint at bottom: 14.7mm The disparity is not poly-cylindrical but for some other reason.
Intonation results taken when playing loud and not lipping. See how to interpret these results on the Model Comparison Page.
For this test, I pulled 0 at the barrel and 1.2mm in the center for this horn.
Intonation summary: It is a pity that a clarinet that plays this nicely would have intonation that I can only approve for a beginning player. There is not much that can be done to improve it.
Key work quality: Typical of Couesnon. This key work is OK, but requires that the player be careful in assembling and disassembling.
This clarinet is most appropriate for: A careful beginning student who likes the idea of playing a vintage wooden instrument.
