Scale 1:288. An ozatrace copy of a plan showing the monitoring and command incident board for all decks on the Tribal class frigate Gurkha (1960). This panel would be on the wall and would light up if an incident (such as fire, flooding or a injury) was reported in a specific location on board. This drawing was drawn by D. Langskaill [Draughtsman at Rosyth Dockyard flourishing 1974].
