Coleman Adjustable One Mantle Lantern with Adjustable Brightness Untested - Brand: Coleman - Model: Adjustable One Mantle - Features: Adjustable Brightness - Country of Manufacture: USA This is a one-mantle lantern. It's recommended that the pump be replaced with a new one. When used last year, it didn't light, and the campground owner checked it and said the pump felt unresponsive, so replacing the pump is probably necessary. I don't know if the gas tubes, etc., through which the vaporized gas passes, are working. Recommended for those who enjoy restoring old camping gear. Other than that, there is age-related dirt, but there is no rust on the main body. * There are scratches on the bottom of the base from being placed on the ground. (Photo 7) It has been stored indoors after use and not left in an outdoor warehouse, so it looks good for a 30+ year old item. Although it's a one-mantle lantern, adjusting the brightness creates a warm atmosphere that LEDs can't replicate. Thank you for looking.
