Truck identification

[Tony Smith]

There is nothing to physically to prevent the gun from from firing except that the barrel cannot be depressed low engough to engage a target unless the truck is facing down a slope. The carriage of the 2pdr gun was clamped into position on the deck of the truck and the 2pdr can rotate 360deg on it's mount. It was generally fired to the sides or rear only because of the angle of shot.
