It had been run, apparently, using automotive gasoline. There was some soot and the generator was choked with carbon. I understand these brass founts can suffer from stress-cracking, but this one looks good so far.
I had access to a friend's beadblast cabinet (pics taken at his shop); I was able to clean the carbon from this generator rod and needle using steel wool, the asbestos rope tube was serviceable and I blasted the generator spring (after this pic was taken)...
Rather than attempt to quench the carbon from the interior of the gen tube, I placed a wire bottle brush into a vise and reamed out the generator tube.
A little water, a little Kroil and some paper towels cleaned up the fount and vent. I washed the globe w/ liquid hand soap and water.
This thing is amazing! What a heart! It burns brighter than most of my other lanterns. Very happy it's mine and that through the information here that Frank Bebb and Bob Hitchcock have posted about overhauling lanterns, I was able to bring this neat little machine back to life...
