Dear Mr. Morris,
Thank you for posting your request on History Hub!
The Box & Reel information comes from the Electronic Army Serial Number Merged File, ca. 1938-1946; World War II Army Enlistment Records, RG 64. Here is the link to all of the information regarding Edgar M. Morris from that record unit. For more information regarding this regarding this unit, please see this FAQ .pdf.
The National Archives at St. Louis houses Official Military Personnel Files (OMPF) from this time period. These records are releasable to the public when the date of separation becomes 62 years from today’s date, but next of kin also may request copies. You may request these OMPFs to view in our local Research Room for no charge. If you prefer, you may also complete an SF-180 form and send it to the following address for paper copies of his record.
