Anyone building columns needs containers by the dozen. 1:72 model jerrycans and fuel drums are packaged accordingly: sixteen cans in one pack, eight 200-litre barrels, mixed sets of three drum types, or modern plastic cans of 20 to 30 litres ten at a time. Spread the small castings over lorry beds, mudguards and depots and a small scale suddenly carries the density of detail you normally see on large dioramas.
