350 Bookkeeper

SSN 350 appears as “Bookkeeper, General” in the September 1942 regulation and supplements, and as “Bookkeeper” in both the June 1944 tentative manual and the June 1945 manual. The instruction “See also 819, 820” is a cross-reference, not an established split, cancellation, or replacement of SSN 350.

Source extraction notes

Predecessor title from the June 1944 tentative-manual column: Bookkeeper. Suggested conversions/remarks, as printed: See also 819, 820. The Present Title column is the manual's June 1945 meaning: Bookkeeper. It is not a present-day MOS equivalence. This is a cross-reference or instruction to review the job specification, not an explicit fixed replacement or proof of cancellation. The table gives no row-level calendar effective date. June 1945 is the manual publication date, not an inferred individual conversion date.
