Source extraction notes

Predecessor title from the June 1944 tentative-manual column: Engineer Supply Clerk. Suggested conversions/remarks, as printed: See also 580. The Present Title column is the manual's June 1945 meaning: Engineer Stock Man. 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.
