Found this in a junk pile, wondering what it is. I'm Looking to restore it if it's anything special
It has a bulb in the circle visor screen, and on the front there are 3 sliders that slide a screen of red, blue, or green over the light. Looks like it take two D cell batteries, and going by what's inside, the buttons on top are on and off. When the 'On' is presses, it pushes a copper fitting into a 'closed' loop, although there seems to be a part missing. Like I said, looking to restore it if I can get a better feel of what it is and what it's for. Thanks.
