After clearing up the area around the entrance, I was finally able to take a photo. This is an aluminum trunk that belonged to an officer of the USAir Force.
It's a little large, measuring 1m across. The tabletop is simple, but there's a letter on the bottom. The lining is damaged, but there's no moldy smell, which is nice. I hope it can be used as both a storage space and a cafe table. Adding a glass panel adds a touch of elegance.
