This scale model of the ubiquitous 55 gallon oil drum has many potential uses. It can be simply a closed container on a shipping dock as modeled in the second image. It can be a fluid dispenser in on the shop floor for multiple possible liquids as in the featured model. And it can be emptied as a trash can as in the third model. Homeless people sometimes use it as a fire pit, Kids and Circus performers (even lions) can use them on their sides for rolling!

I'm sure I will come up with a number of ways to employ these models in my dioramas.
