The thing that I can't work out about the rifle in the OP is how it fits in the case because, looking at the photo, it looks way too long. Did the "creator" of the "bespoke creation" incorporate a "detachable stock" or perhaps the stock is "side-ways-folding", à la M1A1 Carbine?
That looks a lot like an ATI side folder that they sell for shotguns. I have one for a Mini 30. I'd have no idea how he attached it to the Enfield without a stub of the butt stock.
