5 - 6000 miles since the rebuild.

The test was performed by a "professional mechanic."

It doesn't smoke.

I had a friend who lives nearby the present owner take a look at it.

He wasn't present during the compression test.

The friend described the Scout as clean, no rust, and the first Scout
which he has driven which didn't have any squeaks, "real tight vehicle."

He also said, "the oil pressure gauge shows oil pressure."

The friend restores cars for a living, and is knowledgable regarding IHC
light trucks and Scouts.

He seemed unconcerned re the compression.>
