There's a website called Vietnam Huey Illustrations go to the website and click on Medal Of Honor Huey's
scroll down until you see Major Crandel Huey, there's a vector graphic of the Ancient Serpent Six Logo
that he used on the door of his helicopter. The images are Copywrited but you can use them as long
as you don't publish or profit from them. For a one time decal on a model you are allowed to use them.
you will have to print it on decal film from an ink jet printer and I have done this many times and they look great. Hope this helps
