Amduat scene

Been trying to find out a bit more about this scene. It's a fragment of a Third Intermediate Period coffin. I thought the scene was quite unusual.

It shows the sun-disc with arms embracing the scarab. On either side there is an ankh and the symbols for East and West. At the bottom is the hieroglyph showing the rising sun.

As far as I can tell this shows the last hour of the Amduat. The deceased (evoked by the scarab) travels through the Amduat to be reborn with the new sun. Liptay has written on this.

I only know of one other occurence on a coffin (a coffin from Budapest), does anyone know of more?
