I've just been sent a Lachenal New Model English 48 key treble for a bit of a tune-up. Nothing too serious, just a bit slow.
There's one curious thing though. Although the layout appears to be a standard 48 key treble English, both the push and draw reeds for the upper Bb6 (the "northernmost "button on the accidental row closest to the thumb on the left side) are missing, thus creating an "air" button. The slots are all there, ready for reeds but there are obviously no valves or valve pins (notes that high probably wouldn't have them anyway)
Was this standard, or might this be something that a previous owner has done (on the that that upper accidental was hardly ever used)?
I'm asking the current owner whether he wants to keep it like this or have me put in replacement reeds but I'm keen to know what the original might have been.
