Oops, it has occured to me I asked a question in the wrong catagory at this website. Here is where I should have been. My question was " How do you operate a lantern for a Fourth Order Freznel Beehive type?" I can't seem to figure out how to raise or lower the tubular wick, or how long it will burn with a full tank?
