I got into a bit of a discussion of jerrycans around a year ago. Those are a bit off-pattern. They look as though they may be modern plastic ones intended for water. The wartime ones were all metal, with an obvious seam and the spout offset to one side, and the basic design is still in use.

The picture is of a British Army can, still very close to the original design.

The X pressed into the side is one of several variations depending on manufacturer. The German pattern has a plain X. Some wartime US production used an oval ring in a similar way to the square on this.

I have a rather crude model which is good enough for scene backgrounds.
