Had been designed in Germany, started being used since 1940, but almost instantly US copied it 1:1 and started also producing it.
Presently manufactured in large amounts still (80 years since first big production batch).
I have exactly such even today myself.
I've been using this a lot for generators.
@zcream....a new one would serve well for milk, however light weight plastic container might not last as long, but they'd be lighter....which if @Vitaliy ran out of gas on a deserted siberian offroad, or if someone's carry milk from village to village in himachal pradesh, lighter would be better ...far better. And actually I grew up with these in rural texas. They're always so dirty, no one wants to even touch it, much less drink milk from it.
Petrol, it is designed for it.
You use this for what? Milk or petrol?
