[Douglas Greville]

M113 1/2 was the FMC "in house" designation for the Lynx whilst they were developing and offering it around, quite a few countries trialed it.

Once they produced the prototypes it became "Vehicle Command and Reconnaissance" (nothing else) and that is what is on the data plate of that vehicle.
The 2 documented prototypes were known to FMC as "C&R 1" and "C&R 2", both of which were to the original layout with the observer seated to the right of the driver.

Then, when the Dutch bought it, the designation changed to:
"Vehicle, Command and Reconnaissance, Full Tracked, Armored, M113A1 C & R"
Serial numbers beginning with CR1-00XX. Apparently they were hoping to sell thousands......
The Dutch kept with the as built side by side layout, but upgraded to an auto cannon turret for the Commander.

Then for the Canadian contract:
"Carrier, Command and Reconnaissance, Full Tracked, Armored (Lynx).

Nobody seems to know how and when the name "Lynx" came to the vehicle. The issue with the Canadian data plates is that they all appear to be re-issues at time of rebuild, so it is unknown if they are spares supplied by the manufacturer or Canadian produced, thus if the name came from FMC or not.
