WWII USN Phm3c Corpsman LST 284 D-Day

Here is a recent addition belonging to a Corpsman who was stationed on LST-284 during the D-Day invasion June 6th 1944. Although all the marking and ID check out to the sailor it is odd that it has a pre 1943 rear looking crow on the sleeve. I haven't received his records but perhaps he was in the service longer that the rosters lead on. The blue wool was moth eaten and that is why it looks white.
