Just finished several 55-gallon drums, and dozens of Jerry cans.
This Tamayia kit included several German cans, so I glued them in rows together, with American cans on each end, so it wasn't obvious.
The empty drums are made by Tichy Train Group.
I added some hand cranks to a couple of the barrels, but I don't remember who made those.
I also designed a small open sided structure, which will sit roughly where all these drums are sitting. It will provide cover for a workbench, and several loose items on the layout, including most of these drums and cans...
