I am in the process of putting together an army dress uniform coat display shadow box. The idea is to honor my late grandfather's service with a period correct coat with period correct accoutrements. I will need the advice of some of you more knowledgable collector's to make sure I get everything correct. For now here is a pic of the mustard wool coat I picked up as the base. The first question I have is what type of shirt and tie should I be looking for. My grandfather ended the war as a technitian 5th grade.
