Scale 1:288. An ozatrace copy of a plan showing the monitoring and command incident board for all decks for the Tribal class frigate Tartar (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 plan is drawn by E.
