Dear Mr. Hunter,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located 3 series of the Electronics Division titled Records Relating to Ship Electrical Design, 1848-1965 in the Records of the Bureau of Ships (Record Group 19); and Records Relating to Tube Types, 1945-1960; and Tube Type Files, 1935-1960 in the Records of Naval Electronics System Command (Record Group 345). The records are not yet digitized and available in the Catalog. For access to and/or copies, please contact the National Archives at College Park - Textual Reference (RDT2) via email at email@example.com.
We hope this is helpful. Best of luck with your research!
