This is a vintage US Navy Bauer solar still container. I only have the outer box, not the actual still kit that was originally inside. The still was for distilling sea water into drinking water. The box is red, you can mostly read the instructions on the lid printed in black. Some of the words are covered by the remnants of a sticker or label that was probably added later. The owner says her family used the box for decades to hold buttons and other odds and ends. It originally belonged to her grandfather who was in the Navy WWII or earlier. The box is 6 5/8" x 4 1/8" x 2." It has some scratches and dents. JG.
