Kirk, great collection! I just bought a Delta lantern like your Delta Navy Lantern, on eBay. Its in excellent shape, and I want to get it running, but can't find the No. 6 dry cells that it needs. I was thinking of just putting two D cells in holders inside the light to power it. Have you got yours running, and if so, what did you do? Also, do you have any idea where to get a spare bulb for it? I've never seen a bulb like that before.
