Royal Scots Greys

A good example of how misidentification can have an endless life.  Despite what is written on the print, this not a Bren Gun Carrier at all.  It is a Light Dragon Mk IIC or IID artillery tractor but this one seems to have lost its gun.  The image is on more than one website but the knowledgeable chaps on gwargamesp identified it correctly.
