Vickers-Armstrong Cannon Mod 1917

Based on the Vickers-Armstrong British Mk XIX, 99 of these were supplied by the U.S. in 1941 the price of scrap to Brazil, for coastal defense. Were delivered out of ammunition and wheeled tractor, which precluded the transport at high speed and rapid placement in battery. Modified in Brazil in 1942 with the introduction of new wheels, a platform for shooting in 360 degrees and new ammunition, 20% more efficient than the original remained in use until 1998.
