So I have two oil rocker cans and was out and about today. I came across a circular oil can like the rocker but I is in a wooden crate with a latch system. What era are these from and any value associated to them? Also what purpose did the serve? I bought it cause liked it and want to add it to my collection.

Thanks All
Corey
