This badge, shown as made by Stoffel Seals of Nyack NY, is undated. However, Stoffel Seals moved to Tallapoosa GA sometime in the early 2000’s and was acquired by TydenBrooks in 2010. Check the link for all the gory details.
Interestingly (to me), Stoffel Seals made almost all of the domestic airline “kiddie wings” during the heyday of air travel. I ought to know, since I’ve got a ton of them.
