Seller doesn't show a tag, but says he knows what it is. That always makes me suspicious as people with rare items tend to know proof helps their sales.
Obviously this is a factory made bag. Obviously it is made from Hybrid Cordura cloth. As far as I know nobody is making that cloth commercially, so I think it is safe to presume it is original cloth. But is it a legitimate production or sample item for the MoD, or was it a factory who made a sample on their own initiative or perhaps decided to make a few extra quid by running a few "samples" with surplus cloth after trials were concluded? Just curious
