I have a string of small bulbs, about 2 inches each, direct wired (no socket), with what seems like a considerable amount of mercury in them for their size. Some are labeled Maytag, 2-140. I don't know where they would have been used, or for what purpose, or anything else for that matter. It seems strange to have six of them wired to a central bar, also labeled Maytag. It almost seems like they might have been panel lights or indicator lights for something, but wouldn't the mercury make them really bright? Is there likely to be any interest in them since I can't really see them fitting in my collection of mechanical items.
