TTN, loved your story about the Twin Pin. Going totally off-thread, I was reminded of what they used to say about the Pioneer family - you were actually safer in a (single) Pin, because with either aircraft, the loss of a single engine invariably resulted in a rapid termination of flight, and it was twice as likely in a Twin. (Perhaps that could have been part of your gent's defence?)
And that makes me think.... what has happened to the beautiful Primrose, at Mike Collett's late-lamented Classic Air Force at Coventry? I had the great pleasure of flying in her a few years ago, and much enjoyed the roar of two serviceable Alvis Leonideses as she went sideways in a stiffish crosswind....
Sorry, daydreaming....
