Recently my grandmother passed away, and I have asked my mom to inherit my grandfather's military uniform from World War II. I asked when I was in high school about it, and I was told there are no patches or medals on it. My sister and I have decided to restore it as best as we can over the summer, and I was wondering if anyone could identify what this patch on his uniform is. I thought it was a division, but I have not had much luck. My grandfather was at Fort Mason, then sent to Hawaii to go to Okinawa, but he was lucky last minute when they needed a volunteer to be a draftsman, and he got the job (so the story goes). I believe he stayed in Hawaii for a majority of the war, but I am not sure. I found online on Fold3 that he was a warrant officer, but I also have been sent a photo of him by mom and it said he was a Private 1st Class. Thank you for your time and help.
