Thanks to Tom Deats for giving me the privilege of reviewing this clarinet!
Serial #4101, batch mark under keys, 706.
Only the bell has the Kohlert stamp. I think that this is a Malerne French stencil clarinet that is now wearing a Kohlert bell. Where have I seen the batch mark under the low C# key and RH bis key?
Bore LH joint top: 14.5mm
Bore LH joint at bottom: 14.5mm
Intonation summary: Except for the chalumeau D, this is great intonation. Notice that starting on high A it goes way sharp. I think this is because of using a modern mouthpiece with a narrow bore clarinet. Using a more appropriate mouthpiece could significantly help that upper part. That chalumeau D and the throat tone A could be lowered by adding material in the tone hole. With the current problems, this is beginner level intonation only. But with a different mouthpiece and good tweaking, this could become upper intermediate level in intonation.
Key work quality: excellent! While I was working on it I saw signs that made me think this was made for a pro-line. Earlier key work attributes include the throat tone G# without the adjustment screw, the single post for the left pinkie keys. Note the Malerne upper curve in the first right hand pad.
This clarinet is most appropriate for: beginning to intermediate players.
Condition issues noted: Small hairline crack not going all the way through in the barrel was filled and stabilized.
