I've been pottering with the organ periodically, just got to the point where all the reeds are fixed, they all make noises, although there's still two which are sticking. From my rough notes, I think i've worked on about 20-25 keys which were sticking or leaking air.
I've reassembled a few bits, which included finding an old vaseline lid (metal) in the bellows (look, i've got no idea either). And cleaned the keyboard. More pics below.
