Instrument · Converted to 4812, effective April 29, 1949
This code is not in paragraph 5's rescission list or paragraph 6's restricted-use list; only the explicit appendix T/O&E position conversions are asserted here. Instrument positions become instrument-operator positions under 4812. Repeated position-level change-sheet rows are collapsed into this one canonical predecessor event, preserving first-source successor order. The predecessor remains in the SSN namespace; successors are numeric MOS codes.
