In researching my fathers Navy career, I found that he served WWII as a signalmen in the Armed Guard. I am confused by conflicting data on his rate at different times. The records I have from the WWII period show him as moving up from SM3/c --> SM2/c --> SM1/c. This includes Armed Guard voyage reports with crew lists where he is shown as SM1/c on more than one voyage report, etc. I have a picture of him from right after the end of the war, and he is clearly wearing a rate patch for SM1/c.
However, his official Navy records show that he was SM2/c at war's end, and in 1948 when the SM and Quartermaster rates merged, he was a QM2/c. Later becoming QM1/c (June 1949) then QMC. So, official records say SM3/c --> SM2/c --> QM2/c --> QM1/c --> QMC. I talked with a shipmate of his from 1949 who recalled when he made QM1/c, so i believe that is accurate.
Trying to figure out the clear discrepancy. Wondering if there might have been "temporary" field promotions, or some such thing during the war, where guys were "unofficially" promoted.
He was awarded the Good Conduct Medal for each period he was in the service, so i don't think he was reduced in rank for some bone headed thing, and there is also nothing in his service record to indicate that.
