Thibouville Masson characteristics seen on this include: *a batch number under the keys (177Z); *wonderfully wide and comfortable rings; *a hook shape ending the top two left pinkie keys; *beveled tone holes on the left hand joint, but these are surprisingly flat. What I mean is that there is normally a gentle upward shape towards the tone hole, forming a rather sharp lip which makes contact with the pad. On this clarinet, many of the holes are almost flat inside the beveled out area. This is visible in two pictures.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 .5mm at the barrel and 0mm in the center for this horn.

Intonation summary: This seems Way Better than the other Thibouville Masson Harmonie that I tested as one of my first projects with clarinetpages. Perhaps I have changed. This would have been professional intonation in the day this was made, and is still very good today. Somehow they avoided the sharp right hand low tones. The low G and corresponding clarion D could be lowered given the time to tweak pad height and add material to narrow the tone hole.

The unmarked two-line mouthpiece that I found with this horn makes me play very much sharper than with my B45 on this horn. And I didn’t like the response at all.

Key work quality: Good. Very nice looking nickel. The keys are typical of the time when these were made, but they are not as sturdy as today’s best student models. So this is not a marching band horn. The owner should exercise reasonable care in assembling and disassembling.

This clarinet is most appropriate for: Any good clarinetist. This has excellent tone.
