Plugged it in and it fired right up, I was so excited I forgot to take a picture, sorry.
Disassembly is pretty easy, there's already a groove where the front and back case half meet. It was just a matter of running a knife around the groove until I could shear the three connection pins, then it opened right up. What you see is what you get, the two contact pads at top of the element are press fit to the metal studs in the back half of the enclosure which taper into the blades of the plug. 120 volts AC (in my neck of the woods) right across the element, it's that simple.
My initial hope was to cut the element down so it could lay directly atop the CdS cells which would be pointing "up" in relation to the octal plug base. However, it appears that one electrode runs the perimeter of the field and to cut it down at all would sever that conductor and potentially render the panel useless. Being that this entire assembly is built on something like acetate, there is flexibility, so my current line of thinking is to roll this like a tube to line the inside of the can and situate the CdS cells in a periscope type fashion.
