[AT] tractor hauling truck

[Indiana Robinson]

This reminds me of an early 1970's Chevy Vega I once picked up as a "spare"
car. It had more miles than care when I bought it. It was an aluminum block
with the cylinders etched to leave a layer of silicon as a hard wear layer.
"It ran..." It was an early attempt to eliminate sleeve liners.  I never
liked the thing at all and didn't keep it very long.
Here is a page that gives some history:
