Years and years ago, my grandfather showed me his Draft Notice for the US Army for WW2, and then he showed me a pic of him holding it in front of his Matilda II in NA- he was a member of the RTR at the time. I asked how on earth he wound up with a US Draft Notice, and he says few years before the war he was trying very hard to chase down a woman he liked in Northern Maine, and in order to help out wound up getting a full set of US documents. It didn't work out, and wound up moving to England, and then the Army when Munich happened.
Not sure on the story, but the notice and the pic sold me on the overall facts of the matter.
His story on Arras is amusing to say the least.
