Thanks for the new information, I have the dot to the left of the bigger dot under the 10. If I attempt to make coffee with it I will keep it in or next to the sink. I have a few of the non electric, and a couple of the electric, one is the older model for sure. I never had the nerve to use either type. I have used the regular Pyrex glass percolators with the screwed on band-handle assembly, but I need the correct glass stem and glass part of the basket, and the star for the electric burner. That is not a priority at the moment, since I have my regular metal percolators. I didn't notice a similar top style to my new one in the pics in this thread, but re-read most of the rest of the comments. I also checked a few of the sites out.
