Hi Mike, Hang in there. I went through this for last 2 years and the Lord provided. I just picked up a voting booth lantern and was going to post when I saw yours. Stenciled on the front is "Empty Oil". On the back is stenciled "Empty out oil before packing in machine". 1981 is the last date I can make out on the tube. Tne bottom of the font shows where an attachment existed for placing on a post.
