Clamped up. I have a layer of foil between the top laminations and the attached bottom veneer. I sprizted some boiling water over the foil and clamped it down. It's gradually flattening out the warped section, but I'm not sure if it will completely. Binding channels are nice and clean, and there is a tiny piece of the original w/b/w binding in place, so I know what to copy.
Not sure if the number "34" written on the rim has any significance.
I have some highly sophisticated tools ordered, as well as some placeholder hardware.
