Answer: In the catalog description https://catalog.archives.gov/id/17301409 it seems that the dates are missing from the individual pages.
However, the dates are included in the PDF version of the Deck Log. https://catalog.archives.gov/OpaAPI/Media/17301409/content/dc-metro/rg-024/594258-Batch00005/Midway-CVA-41-1975-04.pdf.
Dear Mr. Gardiner,
Thank you for posting your request on History Hub!
We searched Logbooks of U.S. Navy Ships and Stations, 1941 - 1983 in the Records of the Bureau of Naval Personnel (Record Group 24) and located the logs for the USS Midway (CVA) for 27-30 April 1975. These deck log has been digitized and can be viewed online through the Catalog as a PDF. To view the complete log for the April 1975 logs, to include 27-30 April, click on https://catalog.archives.gov/id/17301409 and then under the “Documents” heading click on the red PDF icon. Alternatively, click here to take you directly to the pdf document. Please be patient as it may take awhile for the PDF to load.
Because of an error in the Catalog, the logs for those days are not available in .jpeg format. The problem has been reported to the Catalog staff and will be fixed in 1-2 weeks.
We hope this information is helpful. Best of luck with your research!
