I was just reviewing this thread. And noticed some recommending the 1917 edition, of the Schofield.
That is the reason I bought the Schofield lll, it uses the 1917 text. Not the revision of the 1967 new Scofield.
Old Schofields are like diamonds around here, not to be had, so I bought the schofield lll, after finding it has the 1917 original text.
