Well I guess the engineers at Spragthorpe had to do what they had to do, if it hadn't been for those fuel tank cap hinges for the Mark XIV's who knows what the outcome might have been, the world would have been a completely different place. It also appears that the Spradthorpe engineers could give out current governments some advice on recycling, but my guess that trying to obtain Hobnail Boot lace packets could be a bit of a problem these days, but I'm sure if there was a market for the packets I doubt we would be able to manufacture enough of them so they could be recycled but China might possibly be interested in making them from our recycled rubbish they have stockpiled incase there was ever a shortage of this base material
