I need help finding a source for US Army patches. My dad is a Korean War Vet and I am putting together something for him and need to get my hands on a patch. He served with the "7th Transportation Major Port" tank rescue and unfortunately he longer has any of his insignia or unit patches etc. Google did not turn much up but I may not be doing the right kind of search. Any help would be greatly appreciated. It dose not have to be authentic, I will settle for replica patches if need be.
