Hi, I'm a beginning World War 2 collector at 15 years old. I have Asperger's Syndrome so I tend to become attached to a subject in life, and it appears WW2 became my "thing". Anyway, I recently Picked up a WW2 US Greatcoat that Caught my eye. The tag says 1945 as to when it was issued. And at the top of the coat near the collar, inside, it says:36R. Another VERY interesting feature that drew me to it was the fact that it appears to have some sort of large bloodstain at the bottom I have a plan for it as well. I will be wearing it at the WW2 memorial in washington DC the next time I visit, so that I can bring it to a hallowed a sacred ground in honor of the person who's blood is on the coat. Well can anyone tell me more about it?
