On another note, it strikes me that building a replica, it would be easier to use as a base model one that was covered in canvas rather than a steel bodied aircraft, for authenticity. Apart from the Hurricane and the biplanes were there any Axis fighters, ie ME109 or Focke Wulf which were canvas bodied? It would be easier to make a canvas bodied one than steel. Failing that, how would you replicate a steel body over wooden formers without looking like canvas?
