What in Tarnation?

[RobR'35]

The Diamond T truck company used the hurcules line of engines in their trucks. Diesel engines as well.
Some of these trucks and engines were quite big for the day. Many were employed in WWII for taking wrecked tanks off the battle field.
A good friend of mine that served in the army during that time had said the injection system in the early years was the weak link to the diesels.
Long before my time. But interesting.
I'm very much enjoying your project.
