It can also be purchased as half a redoubt in just the two sections, and also with or without a firing step. It measures 160mm by 80mm externally, and 120mm x 60mm internally, with the height at 32mm.The firing step is 10mm high. The picture shows the models inside on the firing step, and the ones in front at normal game table height. As with all my other pieces, i've tried to add as much detail as possible without over doing things. I think the close up shots give a good idea of how it looks with GW 28mm figures.
Its cast in resin and available direct from me via my Terrain for sale page at £13.49 + p&p.
