Welcome to TreasureNet Jody!
I'm able to enlarge the photos fine, and agree with the O.C.Tanner mark, as they made a lot of wings for both military and civilian (airline) use. I can't match it up to any particular airline, but suspect that that's what they are from. They may have been a stewardess pin or similar application. Did either of you grandparents ever work for an airline? It would also be helpful to know the size.
