Special Forces SOG 1-0 Vest

Vietnam Special Forces SOG 1-0 Vest. Where to start with this killer rare item? Heavy green canvas body. All pockets and details are outlined in a khaki twill materuial. Has a heavy brass 555 zipper. Numerous pockets with silver metal snaps that were painted black at one time.Still has the three leather closure flaps across the front. Hidden interior pockets. The zipper is missing a tooth at the bottom but can still be  zipped up. This one has been well worn and lots of sweat and use staining on the inside. Probably one of the rarest pieces of uniforms from the Vietnam war. Wish it was named but no matter what I was happy to have this one in my collection for a few years.
