Sorry but the answer was completely wrong.
Between the Civil War and WW1 all US military canteens were made in government factories (primarily Rock Island). A canteen with a patent date on it would not be US military. It wouldn't have much interest to US military collectors. Large numbers of similar PALCO canteens are listed often on EBay and do not sell at all.

I found the canteen was made and used by the Japanese and Russians alike and was made under contract for US manufactures. If it is on EBAY you can almost bet it is counterfeit but I stick by my comments that reenactors would pay that much and more. They want to feel authentic even if they aren't!

Hi Gary, It's 10 years later, and I ran across your post while researching the same item. Turns out, it is not a canteen as I thought at all. When I held the 'canteen' up to the light, the front of it is etched "Geyser bed warmer." That would also explain the screw on cap--it's to prevent the water from leaking out into the bed. I don't know if you'll see this, but any future searches may shed some light for another person.
