Tanks and armour need fuel...

In preparation for a developing Eastern Front  campaign I have been completing a few extra tanks and vehicles. Here are a few more Russian T28's and a BA10 together with the all important fuel dump. This will combine with some factory buildings I have to make a slightly larger industrial sector. The bits for the fuel dump are actually n gauge railways bits. The oil drums are slightly large but I think I can get away with them at 6 mm.
