Thanks. I was was able to take some dimensions off the most authentic Halifax left in the world (NA337). I guarantee that I am the only person in this group that has had that luxury. Even still, as someone that produces engineering drawings for a living, I would categorize this as artwork. I was also told by the restoration team that even the drawings from Handley Page were not a perfect match as many components were made from patterns that were modified on the shop floor.
Your point about the props is a valid one, I do have a layer with prop blades but I am not happy with it. I have not tried showing the props in motion, perhaps that is a better solution.
