Gents, just found this on the internet while looking for some China Marine stuff. It is a photo of a very young 1st Lt Robert H Barrow, 1944 in China. He later retired as Commandant of the Marine Corps. He was serving with a quasi OSS unit detailed in this link. What type of gun is he holding. Don't have my reference books here in Norfolk. link to article.http://www.mca-marines.org/gazette/article/marines-china Thanks in advance Sandman1957
