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

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.

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.
