Hi Adam,
I'm a Mobil collector and have seen a couple different windsocks made by Socony-Vacuum (earlier Mobil Corp.) that were supposed to be used at airports. I do not own one as they are 10 feet long and I'd rather use my precious wall space for other items.
Welcome to the site by the way,
Darin
