Here's a Coleman 440 that has not been fired. I tore it down to see as many parts as possible except for the main valve. Of interest: 1. Tank coating, which is pink in color is on the mouth of the tank filler hole and inside the tank. 2. O-ring on the main valve instead of graphite packing. 3. Newness of the burner rings. Never been fired. sam Unfired. Ultralight. Clean. Instructions. Lever. Generator. Retainer. Birthday Coating. Parts. Valve. Pump. Rings. Bowl. Generator.
