Series Description: This series consists of Advance Change Orders (ACOs), which were used to authorize product modifications before the corresponding changes were made in the drawing or procedure documents. The orders include names of requesters and receivers of the ACOs, distribution, reasons for the changes, descriptions of the changes, drawing or document revision numbers, and approval signatures. The records were written either by Sandia National Laboratories, Livermore (SNLL) or Lawrence Livermore National Laboratory (LLNL) engineers or by a Rocky Flats product engineer with SNLL or LLNL approval.
