The rating scale
Tracks are drawn in the color of the rating. The Enhanced Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.

Unrated
The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

What the Weather Service recorded
An intense winter storm and passing cold front caused several tornadoes and numerous severe thunderstorms across Central Alabama.
The tornado that touched down in Tuscaloosa County moved eastward into Bibb County, eventually lifting just north of Eoline.
The tornado touched down just west of County Road 26, north of State Highway 25, and continued across the Six Mile Community, before eventually lifting just west of Ashby. This tornado did not cause widespread damage along the whole path, but there was evidence of sporadic building and tree damage along the entire path.
From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

What this means
Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
