Can't speak to the authenticity of this shirt from a military point of view because of my own ignorance: I bought it to do 1920s upland game hunting in, and for my purposes it could be a private purchase from a contractor equally as well as a war-surplus item. What I can say is that I'm extremely pleased with it as far as materials and workmanship go, and find it a very believable period item. The sizing is correct, but if (as will be the case with me) you either think it will get soaked at some point and/or you may wear it as an overshirt....order the next size up.
