Hi Joe,
Thank you for the picture and link. I'm lucky enough to have an old Monogram kit unbuilt in my garage right now.
Honestly I don't have any idea who flew "Huns" other than than US and France. I did some looking prior to asking for help as I did not find any pictures of shark mouth US F-100's.
To me It seems odd none were painted as such since they were on other ground support aircraft of the period (SEA).
While searching the web I did find a set of decals that had both US and French markings. The French version has the "Teeth". Maybe this is where a Janes aircraft book would be helpful. I will try to look into this more, if it doesn't pan out I might build a foreign F-100.
Thanks again Joe,
Brian
