Summary
The Schneider CA1 was the competitor against the Saint-Chamond and ultimately a disappointment. They were first deployed in 1917 and were already considered obsolete in 1918, but would still serve until the last day of the war nonetheless. However, due to their production being suspended to focus on the production of the Renault FT and their obsolescence, they were decommissioned just after the war. However, they would see service within the Italian and Spanish armies up until the mid 1930s.
Variants & Changes:
1921: Hotchkiss machine guns rechambered for Spanish 7x57 mm Mauser.
1922-1929: Some tanks were modified with an additional two machine guns, one in the rear doors and the other in front of the driver’s position.
1922-1929: Most tanks were modified with radio antenna on the back and rear of the vehicles.
1922-1929: One vehicle, No. 6, modified with a headlamp and a “cage” atop the roof.
I am like >50% certain 7,1 cm doesnt actually exist and was just a missread of 7,7 cm.
5 cm was a rarely used caliber, i dont have much info on.
7,7 cm was the standart.
7,5 cm was for export. Krupp made a couple. The ammo is even in Geschossringbuch I.
