If you can download this photo you can have some one who does machine embroidery recreate it on a hat in the color hat that represents his branch of the Military. Just put it on a USB stick.
We had a Corvette done on the back of a jacket for hubby. His jacket contains many patches from the Ships he served aboard for 20 yrs.
If you want his medals you write your US Rep and provide a copy of his DD214 with a replacement request. Request his service records while you are at it. IF they can’t find them have them look under the VA. Many records were destroyed in a fire.
I was lucky my Dad’s were also at the VA.
