Dear Mr. Lindblom,
Thank you for posting your request on History Hub!
We searched the World War II Operations Reports, 1940-1948 in the Records of the Adjutant General's Office, 1905-1981 (Record Group 407) and located a three-page history of the 975th Engineer Maintenance Company from September to October 1945. For access to and/or copies of these records, please contact the National Archives at College Park - Textual Reference (RDT2) via email at firstname.lastname@example.org. No additional records of the 975th were located.
We hope this information is helpful. Best of luck with your research!
