Dear Mr. Hintz,
Thank you for posting your request on History Hub!
If your great-grandfather left the U.S. Army prior to November 1912, there may be records pertaining to his service at the National Archives at Washington, DC (RDT1). Please contact RDT1 using their email address.
Official Military Personnel Files (OMPFs) and individual medical reports for enlisted men of the U.S. Army who were separated from the service after October 1912 and prior to 1955 are in the custody of NARA's National Personnel Records Center in St. Louis. In many cases where personnel records were destroyed in the 1973 fire, proof of service can be provided from other records such as morning reports, payrolls, and military orders, and a certificate of military service will be issued. Please complete a GSA Standard Form 180 and mail it to NARA's National Personnel Records Center, (Military Personnel Records), 1 Archives Drive, St. Louis, MO 63138-1002.
We hope this information is helpful. Best of luck with your family research!
