Up for auction we have a double bubble Kosher Zion advertising clock. The clock is in great condition. I personally replaced the complete works/motor assembly  with an as close to original as I could find from American Time & Siginal. The power cord has also been replaced. Both reverse painted glass panels are in good condition.  The clock runs, lights and keeps good time. The light source is 2 regular incandescent bulbs. I will double box and pad well for shipment. Insurance will be added to the final invoice. Thanks for looking.
