I purchased this item over 40 years ago at an event selling used aircraft-related goods, and it has been stored in a storage room ever since. It's a rugged stainless steel construction, weighing a hefty 910 grams. While it seems unlikely to have been used on a passenger aircraft, the JAL mark on the top (see photo 2) suggests it was indeed in service. There are no signs of heat damage on the bottom, indicating it was likely used as a pitcher. I'm unsure if it can be used as a kettle over a fire. Although it has scratches and shows its age, the handle and spout are secure, and there are no leaks, making it still usable as a pitcher. I believe this is a rare item for aviation enthusiasts. Height: 24.5cm, Bottom Diameter: 12cm Capacity: Approximately 1.8 liters Thank you.
