Dear Frank Croce,
Thank you for posting your request on History Hub!
We suggest that you request a copy of his Official Personnel File (OPF). OPFs and medical information for individuals who worked for the U.S. government in a civilian capacity prior to 1952 are in the custody of the National Archives at St. Louis, P.O. Box 38757, St. Louis, MO 63138. Please include the full name used during Federal employment, date of birth, Social Security Number (if applicable), name and location of employing Federal agency, and beginning and ending dates of Federal Service. For more information, the web site is https://www.archives.gov/st-louis/civilian-personnel.
We also searched the National Archives Catalog and located the following entry which may be of interest to you:
Records Relating to the History of the Philadelphia Naval Shipyard, 1801 - 1994 (National Archives Identifier 66539289). Record Group 181: Records of Naval Districts and Shore Establishments.
We hope this is helpful. Best of luck with your research!
