This is an aluminum water bottle, likely from the Showa 20s-30s (or possibly earlier), and it is unused. It has "Taiko" (太閣) written on it. I wonder if this was the manufacturer from that time? As expected for an item that is 70-80 years old, the cork in the inner stopper had disintegrated, so I found and attached a silicone stopper of the same size. The aluminum fitting on the head of the silicone stopper was attached from the beginning. The strap was also discolored, so I washed it and cleaned it up. As you can see when compared to the plastic bottle for size reference, it is a very cute, small size. I believe a new one with this exquisite form and size is rare. Please understand that this is an old item and no claims will be accepted.
