Dear Mr. McCaul,
Thank you for posting your request on History Hub!
According to the Department of the Navy records management regulations, only the deck logs of major combatant and support ships are considered permanent records and eventually accessioned into the custody of the National Archives. Other types of logs (engineer, engine room, quarter deck, sick bay or sick call, radio, and quartermaster) are deemed to be temporary records and destroyed by the Navy after initial administrative use.
We searched the National Archives Catalog and located Muster Rolls and Personnel Diaries, 1/1941 - 12/1980 that may include muster rolls for NAVCOMSTAPHIL's Detachment Alpha, Company L, Marine Support Battalion listing you either leaving for TAD or being received for a TAD. For access to these records, please contact the National Archives at College Park - Textual Reference (RDT2) at Archives2reference@nara.gov.
Due to the COVID-19 pandemic and pursuant to guidance received from the Office of Management and Budget (OMB), NARA has adjusted its normal operations to balance the need of completing its mission-critical work while also adhering to the recommended social distancing for the safety of NARA staff. As a result of this re-prioritization of activities, you may experience a delay in receiving an initial acknowledgement as well as a substantive response to your reference request from RDT2. We apologize for this inconvenience and appreciate your understanding and patience.
We hope this is helpful. Best of luck with your research!
