Today, there are several available extreme-pressure greases that likely would have exceeded the needs for those Engineer's application.

Brent, I am not disputing what you write I just have a question. Did Ford really use 600 wt. oil and what you refer to using in your steering box or was it more like what the vendors today call 600W which I have been led to believe is closer to SAE 140-250 wt. oil according to this chart?
Also what “scale” was used for the 600wt. oil?
Gets kinda confusing.
