In my opinion they would appear to be patriotic/sweetheart wings, as they aren't of the (more solid) construction of any military wings I'm familiar with, and they seem a bit "fancier" than military wings. My guess would be that they were from the WWII years. However I can't say I've seen any just like them, but there was quite a wide range of patriotic items then. Still a nice collectible even if this is correct.
