The Baron's Den is proud to present this historical piece from an estate of a McDonnell Douglas engineer, right here in central Florida. One of a kind item and super rare to find out in the wild! Perfect addition to any collection. Dated September 1989, this four page paperwork is an appendix (even marked Appendix D), showing the material defect codes for various defects. Does not say what project this is for. All four pages are stapled together. In pencil in the top right corner is a name written in pencil. Paper is beginning to yellow, with some wear and tear around the corners and edges.
