Here's some information that may be useful to a few members. Edited Link: OldColemanParts.com | Technical Assistance All about coleman lanterns & stoves.
Somewhere up at my cabin is an Coleman original patent pending lantern. We used to get 12 hours on one tank of gas with it. Then we noticed they tweaked the regulators to give about 4 hours max with a tank full. I think they're a little more than 4 hours running time now but certainly not the 12 hours the patent pending model had. But thanks for the link...I was looking for hours one day for something like this.
Posh! Old Coleman lamps work as well as they did when new! Assuming they are serviced every couple of years. Where do these notions come from!

Thanks @Illini Warrior , the original post was 5 years ago so I'm not surprised the link didn't work.
