BUFFET  CANNON  A PARIS IN FRANCE IP (?)

Hi Everyone!
Can anyone point me in a direction with this clarinet?
This was passed down to us within the family, and I've tried hard to identify it.
It looks like a lot of other Buffet clarinets, but has an unusual looking key on the top right, (as pictured.)

23" Without mouthpiece
26^ With mouthpiece
The mouthpiece reads, 'Henri selmer paris hs."

The nomenclature is very worn. I have examined it a great deal under a magnifying glass.
One part of it appears to say, "Cannon & Cie", although Buffet "Cannon" seems impossible to find out there on the internet.

Another part of it says another name --  "_____ & Cie," that I can't fully make out.

GULRIAC ?
GUMNON ?
GIOMRON ?
GULMNCNR ?
GULMNAR ?
GIAMNON ?
CIAMNON ?

And what key might this clarinet be pitched for?

Any help with this would be greatly appreciated!

Welcome!

Your clarinet "cartouche" says:
Buffet
Crampon & Cie.

That unusual key you are referring to is the wrap-around register key.  That clarinet is over 100 years old.  It appears to be keyed in Bb, and as for pitch, it sounds like you see an "LP" stamp, so it is keyed in modern pitch (A= 440-442 hertz). You have a Boehm system clarinet, and of course, Boehm's new system, designed for the flute, was made possible for clarinet by the creative genius of two other men; Hyacinthe Klosé and Auguste Buffet.  Because it is stamped, it was almost assuredly manufactured after 1894.

Unless you also see "Made In France", stamped lightly into the top joint under the cartouche (typically; sometimes it is on the back), it was probably also manufactured before 1907, or is not an import model.

For years and years I thought my Buffet clarinet said "Champon!"

Nice clarinet, old school Buffets are generally pretty nice. I always loved the wrap-around key as well, it just lends a bit of elegance that i think is largely lost with the modern register mechanism.

I agree, Dave.  I prefer them aesthetically.  I have heard the solid argument for their abandonment; they were more fragile, and more prone to misalignment.
