I did this same thing for my former step-father, who served in that squadron in the late 60s, early 70s. My mother had a photograph of one of the Orions that he worked on, which I then was able to use to track down a high-resolution scan of the logo. I then printed my own decals.
I'm pretty sure I still have the file I used to print the decals, but I'll have to dig it up. I'd certainly be happy to share it with you if it is exactly what you're looking for.
And on that note, I must also add that my step-father passed away just last week.
