I've been worrying this for a few days and getting nowhere. Does anyone know how to remove the (incorrectly-installed) elements in this lens cell?

I assumed the threaded part that attaches to the shutter would unscrew from the barrel of the cell. I don't see how else to get the glass out, and I don't believe the elements were spun in as someone has had them out before and re-installed them wrong. I assume they're installed wrong because both outward faces of the glass are concave, and there's no way to get this to make an image at any focal length.
