A 1st pattern jungle jacket badged to a US Special Forces advisor to the LLDB (the Vietnamese Army Special Forces). The shirt has full colour insignia, note the Ranger qualification tab worn at the top of the left shoulder above the SF insignia. This shirt has a repair to the collar/rear neck and a few spot repairs. This is not uncommon on early jackets and trousers. Because they were only available in small quantities early on, those that had managed to get them made sure that they kept them, as the alternative was the heavy (and therefore hot and uncomfortable) OG-107 uniform.
