Thanks! That's the approach I'm taking. Bellows airtight first. Then a period of reflection on the tuning before the next step.

The good thing about harmoniums is that they have clearly defined layers, and each layer can be approached left to right.

The things that worried me were the steps that are difficult to reverse without the risk of damage, like gluing and tuning. I've done some of both now!

Curious about that mystery instrument. Give me a clue.

I've found it! The 'clue' was that the name contains 'lion' but I still couldn't find it and then suddenly it popped up. Pedalion.

They are fairly big compared to your typical harmonium.

They're a funny half breed, they have a blower motor, use reeds instead of pipes, and were popular with churches as practice instruments.

Oh, and this might interest you if you haven't found it yet:
