Those older lanterns had a pump up valve, drop a drop of oil around the shaft of that valve and give it a few pumps to see if it will still get pressure. If not drill a hole in the bottom wire it for a bulb and make a lamp out of it. If is dose get pressure open up a couple of shot gun shells and bump the bbs into the tank and put a small amount of fuel in. Replace the cap and shake hard, make sure you turn in upside down while shaking. This will knock the rest loose. Dump fuel and rinse once more and you should be good to go. You have to rember that those old lamps had to warm up to work so when you first start it you might get some flame comming out the top. Be sure you are in a clear area when you light it up.
