Yes, "blue" was an onboard ship dixie cup color pre-war, but my dad did not get one in 1943 when he came in. It used to signify a sailor "on duty", correct? My dad got the whitie tightie only, which went with dungaress, whites, and dress blues, situational dependent, and he also had the Donald Duck hat with the little cut ribbon hanging on it, for full-dress blues. But his main onboard cap was the N3, which was distributed beginning in 1943. Unfortunately, we cannot "date" the clothing worn in the crew files, but we do attempt some control in the conning towers, or UnitParts files.
As for the BAR, we might be able to mount a 50cal mg to the bridge wings... have it show along with the crewman during Battle Stations... But that would be a bit of an undertaking... If there were any "commands" left, we could do an "Easter Egg" button combo that would put a fellow like that on the cigarette deck, but alas, all the slots are taken... I don't know as the game has a way to have a rifle shoot though... I have shot at mines with a 20mm, and they will blow-up from that, but man, talk about a tough chore...
I don't know how long this image will be up:
