Been reading Bill Munro's "Alvis Saracen Family", he mentions that in 1960 Alvis were designing a one ton all wheel drive Army truck to be fitted with the Ferguson centre differential. As Alvis have designed some of THE most interesting Military vehicles I am keen to know more about this (assumed) dead end. I am sure I have seen a picture with a prototype in the background, but can't seem to find it now.
Any details to apease my curiosity would be greatly appreciated.
Rich.
