Jack H. Smith, Mustangs & Unicorns, and USAF Historical Research Agency website credit Archibald with five victories in one day, 18 December 1944, the day that he was shot down; these victories are not recognized by USAF Historical Study 85 and he was not officially credited with any victories or with ace status when the study was completed in 1978. Captain Archibald's presence on the USAF HRA website may indicate that his case has been resolved to reflect the victories of 18 December 1944. The victories are not recognized in Kent D. Miller, Jigger, Tinplate & Redcross. Listed as RTD by MACR 11302; account of Prisoner of War (POW) experience appears in Jack H. Smith, Mustangs & Unicorns.
