I guess this is somekind of Prototype?, never seen it before and as yet have not been able to find any references to it.

The Crotale EDIR (Ecartométrie Différentielle InfraRouge, "InfraRed Differential Ecartometry") is an all-weather short-range anti-air missile, which can be used to intercept low-flight anti-ship missiles and aircraft. In 1964, South Africa placed a development contract with the French company, Thomson-Houston (later Thomson-CSF, Thomson-CSF Airsys, which then became Thales Defence Systems) for a mobile, all-weather, low-altitude surface-to-air missile system. The Electronic Systems Division of the then Thomson-CSF was prime contractor for the complete system including the radar and electronics, and Matra was responsible for the missile. In February 1971, the French Air Force placed an order for one acquisition vehicle and two firing units which were delivered in 1972. After extensive trials with these units the French Air Force ordered the Crotale (Rattlesnake) system for airfield defence and by late 1978, 20 batteries had been delivered. In 1975, Saudi Arabia ordered a new version of the Crotale, mounted on the chassis of the Giat Industries AMX-30 MBT known as the Shahine. The Saudis also ordered the standard Crotale in late 1978 and an upgraded version in 1990 for their air force.
