Documented history

Title not stated in source

30 June 1945 is the publication date of Change 2, which contains the table. The entry gives no effective deletion date, so 1945 cannot be treated as the confirmed year of deletion.

  • The table does not state the title or duties of SSN 3531.
Source extraction notes

Appendix I lists deleted SSN 3531 with suggested substitute 864. The table does not print the deleted specialty title, so the neutral title placeholder is used. The row-level deletion date is unstated. The citation dates Change 2 to 30 June 1945; that publication date is not an effective deletion date.
