| Notes | Another Hotchkiss design that was refused by the French army, the CA 25 was finally adopted to fill in the void left by the late development of the 37mm Schneider anti-aircraft gun. Due to faults found with the original mount, a new mount and carriage was developed. This late improvement was to hamper production and only around a few hundred of the new models were issued before the German invasion. The weapon was also adopted by Japan and Romania. |
