19th Century Music Box, Blackened Mahogany Case, Fir Base, Two Tunes To Identify

Beautiful old music box in working order which seems to play at least two different tunes, the mechanism, roller, movement, comb are made of steel and brass, the pivot heads of the axis seem to be rubies.
The pins are all present and in good condition, in fact the music tunes are beautiful and the game does not seem to have any gaps or false notes, A small glass shutter protects the mechanisms from dust, on the left side a small arm of lever is used to wind the barrel spring and on the right side small levers seem intended to change the air and stop the movement (I don't know enough about this to tell you more).
Apparently, after some research, this music box played eight tunes and was made by the "Fabrique de Genève".
The structure is made of solid blackened mahogany, the base is made of fir. I can possibly send you a video which will show you this music box in operation and which will allow you to simultaneously listen to the two tunes which seem to be played.
Note a slight oxidation in certain places on the steel parts, but really very scattered; few things.
