Just a comment on Fitz's item 1. I have noticed on most replicas the complete lack of "positive" locking devices. Split lock washers are not really locking devices (they relax with time and then are no better than a flat washer). I have replaced all the nuts that I can with "elastic stop nuts" or Loctite. Also where possible the fasteners are replaced with AN or MS standard ones. All parts that are subject to rotation must us positive stop nuts (see AC43-13).
