Bradbury sounds right for this hymn. Vaughn was just claiming the arrangement. The copy mentioned above shows a good example of the Aiken 7 shape system for anyone who thinks shape note books only come with 4 shapes & oblong.
The old thread says it's in the Southern Harmony. It's not. It is in the appendix of the J.L. White revision around 1910. If you see a 4 shape version with the air in the tenor, it's ultimately a copy from that.
