Or,,,,, is the real explaination that he came from the future, where they have been at war for years in order to sercure the very last brake adjuster and knows when it starts, so in turn sells them to the needy in order to prolong the peace long enough for his own future ..
Or maybe,,,,,,,,,,,,, the truth is just to incredulous to believe .......
