Eagle device

[1dirtyknee]

Found this last week as well. I think it is aluminum. It has a sew-on shank, like a button, on the back. No markings that I can see. Has an eagle facing to the right and a shield design on the chest. Looks like it had feet/talons at one point, but they are gone. Found in same place as previously posted lead item.

 

[CRUSADER]

I would guess military capbadge (or pin as you say)

 

[Snowdragon]

Possibly for a bolo tie?
