The original gun was the Russian M1902 which the Poles had captured in large numbers and re-designated it Armata 76.2mm wz. 1902. However, between 1926 and 1930 these were re-chambered to use the more common 75mm and re-designated Armata 75mm wz. 1902/26. It was crewed by 6-7 men with a range of 8.5km and a rate of fire of 10-12 rounds per minute. Around 400 were used. Following the defeat of Poland in 1939, the Germans pressed the gun into service where it was designated 7.52cm FK 02/06(p).
