On the ring it says "Bombardier USAAF"

The wings are WWII bombardier wings. Called a bomb aimer by the Brits. USAAF is abbreviation for US Army Air Force which was the name change from US Army Air Corps made during WWII. The USAF did not exist until it was established as a separate service. That was in 1947 IIRC when the name of the War Dept was changed to Defense Dept.

Cool thanks! I found them at a clean up.

those are cool.

my maternal grandfather served in the 8th during WWII. We have some of his memorabilia.

As a prior active USAF and current NJ Air Guard munitions technician I must say AWESOME FIND!  These things are very cool!!  Congrats man! I have been building bombs and missiles with the AF since 02. 

Check the wings for markings a lot of insignia of that Era was sterling silver.
