Clark WW2 Aircraft Tow Tractor

The tractor in question was brought to the UK by the american airforce in 1942 to be used at the airbase at Burtonwood near warrington in Cheshire.
We believe it was used to also tow bomb bogies . It is 2 1/2 tons but is only about 4 feet tall. Low enough I suppose to get under aircaft wings etc.
After the war it was sold to a Paint Manufaturer in a place called Darwen , in Lancashire to be used to tow low slung trucks around the works.
It was used as such until it was to be sold for scrap in the late 1990's.
The present owner worked and drove this tractor for the paint manufaturers for many years and on his retirement bought it for sentimental reasons.
He has since restored it to as original condition and occasionally uses it in local calvalcades and fairs as an exhibition piece.
Really we want to find out anything we can about
it.

Do you know or have any other knowledge of any others around?

Thanks.

I have now completed scanning all of Clark's old specification sheets and will be happy to send you JPEGs of the specs for your friend's Clarktor.
Please advise.
