I got my TIE pilot yesterday that I'll use for my Luftwaffe pilot. I just carved his head up, I haven't made the skull cap yet but I began experimenting with the mask straps. I haven't used Verlinden lead foil before, never had a reason to, but its a great product. It cuts very easily and its very soft but strong. Much better than using aluminium foil. I'm not sure if its real lead or not, so I might get lead poisoning before I finish. You can use Verlinden lead foil for straps, belts, gun slings, capes hoods and many soft goods.
The reference picture on the bottom shows that the Germans did use a white pilot uniform. It could be a winter bomber, but its just a drawing though, I haven't seen a real one. It will make a great WW2 AT-AT pilot reference.
