Hello all,

A guy at work brought in a beat up cornet in need of professional help. It belonged to his Grandfather.
On the bell the inscription read ...

Gonet et Cie
Paris
C & C
New York
Sole Importers

I could not find a serial number anywhere and the only other markings were the valve numbers.

Does anyone have any info on this brand?

Thank you,

David
