Dear Mr. Barker,
Thank you for posting your request on History Hub!
We searched the Records of the Bureau of Naval Personnel (Record Group 24) and located deck logs of the USS Perry (DD-844) for 1968 & 1969. For access to and copies of these records, please contact the National Archives at College Park - Textual Reference (RDT2) via email at archives2reference@nara.gov.
We hope this information is helpful. Best of luck with your research!
