Experimental Image Orthicon 5820A Tube

[julianburke]

Has anyone seen a RCA experimental 5820A image orthicon tube like this one that has perhaps a night vision intensifier looking addition on it? It has a (red) RCA label touting it as experimental only and the intensifier is all professionally annealed to the glass tube itself as this could only be made at the manufacturer. All of the swirl marks on the metal drum are some sort of a glue or adhesive that was scraped off. There are also two electrodes on the drum.
