Negative information. A bit unusual, but no joy on fold3.com other than draft registration card. Assume you have US Veterans' gravesites info: PVT US ARMY, service st. date 20 Feb 1923.
His obituary has "He was a supervisor in Public Works at the Pensaola Naval Air Station having worked there for 31 years prior to his retirement in 1959." Below that: "He served in the United States Army and the United States Naval Reserve before his employment at the Naval Air Station." Sort of implies that he joined USNR after stint with Army. Message me and I'll send you the obit if you want it.
