Anyone feel free to correct me if I'm wrong with the following.
I believe that HO 211 (Ageton)was the first sight reduction table "commonly" used in this country. That would have been in the 1920's or early 1930's. HO 214 came later well into the 1930's possibly early 1940's. If what I remember reading was correct, some of the work on 214 was part of the WPA.
