 Because of the danger of bombes at Bletchley Park being lost if there were to be a bombing raid, five bombe outstations were established, at Adstock, Gayhurst, Wavendon, Stanmore, and Eastcote.The bombe was referred to by Group Captain Winterbotham as a "Bronze Goddess" because of its colour.The devices were more prosaically described by operators as being "like great big metal bookcases".
