Comparing: Spähpanzer SP I C vs. AMX 13 57 GF

The reconnaissance tank destroyer was being developed by Hotchkiss and Klöckner-Humboldt-Deutz companies from 1956 through 1962 in order to increase the anti-tank capability of recon tank battalions. A 90-mm anti-tank gun was planned to be mounted on the new vehicle. The project was eventually declined. The number of prototypes built is unknown.

The AMX company conceived this light tank, which was to mount the 57-mm L/100 gun. Problems in development slowed the project, and by the 1950s the vehicle was still not ready for presentation. By that time, the production of a modified chassis with the turret mounting a 75-mm gun had taken precedence, and the 57-mm version was discontinued.
