488 Gauger, Petroleum Products

Appendix B identifies SSN 488 as “Gauger, Petroleum Products” under AR 615-26 of September 1942 and its supplements, and suggests SSN 485 as a possible replacement. This was not an automatic conversion: each affected Marine’s Qualification Card had to be reviewed against the job specifications before a replacement was selected.
