Removing celluloid.

No to both. Two reasons. Firstly, I don’t use a thumb strap and it’s the the only box I’ve ever had with a convex edge. My thumb slips off. It doesn’t need a groove but it must be at least flat, perpendicular to the plane of the buttons. To do this I need to compromise the red-celluloid edge. I don’t know how to this neatly.
Secondly, when the treble is finished I’m ‘marrying’ it to a black bass end. If I can remove celluloid relatively easily I could end up with wood on both ends.

I have no experience with removing celluloid, but there is a discussion about it on melodeon.net
An alternate suggestion: Maybe you could fabricate a thin hardwood strip, flat on one side, concave on the other, and then fasten it to edge of the fingerboard using double-sided tape or an appropriate glue. You can then paint the celluloid black, if you want a black accordion.

If it was mine and I absolutely had to have a flat surface with 90 degree corners, I would put a 40 grit belt on a belt sander and sand it down on the end. No use removing the celluloid, just grind it off. Then I would use a piece of ebony or rosewood and glue/screw it to the flat surface at whatever thickness you like. If your sanding was done right you would not know it didn’t come like that. You would not need to finish the rosewood or ebony. Sand with different grits to 600 till it shines and add a coat of wax. Would feel nice to your thumb too. Not like the plastic which might get a bit sticky feeling when sliding on it.
You could also cut the edge off first on a bandsaw and then sand on the sander. I don’t know what kind of luck you would have running the edge through a jointer.
