Dad bought this piece of US military surplus when I was about 3/4 years old and vowed it would be the last thing he ever sold:
You'll notice the diff on the front axle - yep real traction. The winch is missing from the front, but its partner at the back could drag a D8 out of a hole. The stays on the jib were locked down to the chassis to increase the lifting capacity. I have a picture somewhere of Tiny being used to pull down a crusher plant, breaking a couple of wire ropes, the last one being over an inch or so thick. Maybe it was already damaged. In polite terms I was very frightened when the rope reared up and made its way back...
It was manufactured by Ward-Le-France in the US, and was initially equipped with a guzzler (and I don't mean 10mpg either!) of a petrol engine, promptly swapped for a diesel.
If there's any interest in this sort of stuff I'll pitch some of the "family album" up onto the website (given time!)
Best Regards
Steve
