Good morning. The box on a cylinder looks like a dradel. I may have spelled it incorrectly. That is back up by the fact that you had indicated that your grandfather had many Jewish friends. That might also play into the image of the light. The Jewish faith has a holiday called the Festival of Lights. Of course, the only way to really know for sure what the meaning of the images are would have been from your grandfather. Either way, it is a very nice piece.
