My No. 2 has a dietz globe that has "v" shaped raised things on each side for the globe bails to hold the globe in place. I have researched it and it was made around 1955 just before the change over to True Value, and these lanterns were no longer made. I had to remove a light overall surface rusting as much as I could and planned on taking it to a metal coater in order to get the lantern regalvanized since it didn't have any paint on it whatsoever to begin with. I didn't know they were going to dip it in acid to prep the metal before galvanizing and the acid ate through the solder that held the star wheels that moved the wick up and down. When I got it back I discovered that the star wheels were completely loose. Since these wheels were soldered on the wick riser rod when it was first made I had no way to get in there to resolder them back on the rod. So I have to cock the wick riser as I turn it to get the star wheels to hang onto the wick well enough to raise it up and down okay.
Other than that this lantern is one of my best and I am using it right now to warm my little shop up this winter along with a couple of other kerosene lamps.
If you figure this lantern is over sixty years old and I will keep it as long as I am alive there's no telling how long it will last. The No. 2 wick puts out a bright enough light to do most of anything you need to do outside at night.
The only thing that would come close to being as good would be the big Dietz lantern with a No. 2 burner and a 30 oz. font. I think this HSP I have is over 20 oz.. It will burn for about 12 hrs. at least.
