Found this unassuming beastie at an antique store for a modest price and figured this would make a nice addition to the collection. Darned if I can figure out the model or date of manufacture. Very well made, simple and easy to clean up. Looks like someone may have broken the original glass in the 50's or so and put a Coleman one on. Also has what looks like an R55 Generator. I also discovered the whole burner and tubes were all steel instead of the usual brass that you see in Coleman lamps. Someone wanted these to last.
