Close up of loops for swallow's nest. Also notice he has a rank disc, but the stripe has been removed. Was he demoted? Why not just remove the disc. No rips underneath
It looks as it ( the blouse) might have been stripped at one time as the buttons appear to have been replaced ( I could be wrong though. It will be easy to restore the DJ rank roundel as they are easy to find on most dealer sites .
Joe, Who knows about the buttons, but I do believe the rest is period as the shoulder board was shortened and had a loop added to it for the swallows nests.
