It's a small green shot made for Shonfeld's USA. It's microwave and dishwasher safe (how often to you microwave stuff in a shot glass?) I didn't have one, so I do now.
I also found a General Electric PC-1 Color Control Meter. I can't figure out what the heck it does but it did some with a bunch of little plastic cards that go in the device for different kinds of light (I think.) It comes in a handy carrying case that seems to allow the device to be mounted on something (tripod? camera?) while still in the case. The cover unsnaps and both the front and back are out of the way. Maybe it has batteries somewhere. I can't tell. It's small and heavy for its size. Maybe Mike can figure out what to do with it.
