The Quartermaster hood stick set is all there! It's quite robust and probably should be, considering the size of the canvas.
I've had all manner of Land Rover canvases (Series and Defender 3/4 canvas; Tickford and belt rail NAS) and the common thread between them all is shrinkage. It took me a few times to learn that a brand new canvas needs a solid 30-days to stay snapped-in/tied-down in place or I risked losing a lot of distance between the tailgate/side tabs and canvas. Long-term exposure to rain and sun gives a new canvas time to "cure." It's certainly tempting to skip this step, but I highly recommend sticking out the wait to be sure it can secured without tearing out your thumbs.
Here in the US, the 1994 Defender 90 was introduced with a true canvas top with snaps, but no one told owners to leave it in place... the rear panel was typically left rolled up, so by the Fall of that year, there was as much as a 2" gap that couldn't be fixed. There were warranty repairs to replace that panel, but eventually LRNA (Land Rover North America) went with Besttop for a vinyl-style with belt rails. It just wasn't the same aesthetic as canvas, but the convenience couldn't be argued with.
I will be curious how the sides mount - if they are also snapped into place like the rear or if they have a belt rail design. My guess is that the sides can't be rolled up, as the one in the video only shows plastic clips on the rear - ostensibly to roll up the back panel. Regardless, I am somewhat surprised that even the rear panel lacks a clear window. If that's the only version from the factory, I predict we'll see most in the rolled-up position. Visibility will be quite limited, but damn doesn't it look cool!
