Hi Kevin, please just don't take my word alone.
Sometimes they lack the stiffening material in between the webbing.
I have one original in my collection.
These items are well faked and have been for a few years now. Sometimes the hardware is actually original but taken from scrap tornister packs etc. You can see a fake ( sold as such) here

Even a fake costs £60 or about $100.
Cheers, Ade.
