I have a Busson flutina which obviously needs attention, as the notes, especially when the bellows are pushed in, are not clear - there are high pitched notes almost like harmonics sounding as well. I apologise for my lack of the correct terms - I'm an oboist by training, and this flutina was a lovely gift.
As the entire top part seems to be in one piece, and the flat wood will not slide out from one end as I have seen others do, how do I access the mechanism? Obviously someone has tried in the past, as the lovely painted section on one end has been split.
All help and suggestions are very welcome indeed!
