How many of you still use the metal oiler cans? I have an old one I inherited from my grandfather. He was born in 1908 and this can looks pretty old. Maybe 40's or 50's? It comes in pretty handy. I thought about buying another one or two. I could have one with atf, one with motor oil, one with Marvel, etc. But it doesn't look like anyone still produces them. There are plenty of vintage ones for sale, but it seems like something handy like this would still be produced. Are people just using plastic now?
