Macnamara's Plotter was an unsuccessful pneumatic range plotting device intended for use on the Mark IV Dreyer table to plot automatically plot range cuts from multiple rangefinders. It was designed by Lieutenant Patrick Macnamara in 1914, but was deemed unsatisfactory in some way, in all probability by being too intricate in function. On 6 July 1914, the decision was taken that the Mark IV tables should use the very simple Brownrigg Keyboard to plot their ranges.[1]
