Hotchikiss SP-10 APC

[Petrus]

At http://www.servicehistorique.sga.defense.gouv.fr/02fonds-collections/banquedocuments/materiel_armement/notice_armement/plan/HOTCHKISS%20TT%20AMPHIBIE/HOTCHKISS%20TT%20AMPHIBIE%20notice.pdf you may find a brief description of an amphibious APC built by the Hotchkiss-Brand company sometime in the 1950s that had been based upon a Hotchkiss SP-10 APC. The pdf-document contains some info on the APC's weights (7,000 kg empty, 8,800 kg with fuel, crew and troops on board), but lacks any further info e.g. on its dimensions, planned armament and so on. As for its performance the document mentions the basic, non-amphibious SP-10 vehicle.

Does anybody know anything on the Hotchkiss SP-10 design?

Below here are photos showing the amphibious vehicle. Any additional info on that as well as any pictures would be welcomed as well, of course.

Best regards,
Piotr
