Can anyone help me ID this flag. All I know about it is that my grandfather brought it home with him from WW2. As with most WW2 vets, He never really talked about where he got it, how he got it or anything related to the war. Rumor was he got it off a boat but i thought navy rising suns were offset on the flags. Obviously it's the rising sun but not sure about the symbol on the flag itself. Any help would be great.
