720 Airplane Wood Shop Chief

Appendix B identifies SSN 720 as Airplane Wood Shop Chief under AR 615-26 of September 1942 and its supplements, and suggests SSN 550 as a possible replacement. That suggestion was not an automatic conversion: each affected Marine’s Qualification Card had to be reviewed against the job specifications before assigning the appropriate specialty.
