880 Teletypewriter Communication Instructor

Appendix B identifies SSN 880 as Teletypewriter Communication Instructor in the AR 615-26 September 1942 and supplements column and suggests SSN 237 as a possible conversion. This was not an automatic replacement: each affected Marine's Qualification Card had to be reviewed against the job specifications.
