Mouthpiece receiver (a little old-fashioned for the time, being round rather than more rectangular) may not be original, as it looks like it has widened to accommodate a modern mouthpiece. It does not work with a known French Ophicleide mouthpiece.
Keys 4 and 5 are linked. Keys 9 and 10 have key guards, indicating possibly military use.
