Went to an auction over the weekend and bought this. Sorry the pic is sideways.

This is a US World War Two patch. As issued to personnel of the Army Air Corps who were trained mechanics. The patch was worn on the sleeve and indicated the type of work the person executed.

Bottom Left- WWI trench art from the Battle of Verdun. Engraved 1914-1919 Verdun. Made from a bullet.
Center- ? Hard to research, but it could be gold. It's a tie-tack. Could be a Major's tie tack.
Center Right- WWI The Allied Victory Ribbon w/3 stars signifies 3 different campaigns.
Bottom Right- (it's upside down) The golden eagle was the ruptured duck, . it was a slang term for the Honorable Service Lapel Pin given American military service members who were discharged under honorable conditions during WWII. The pin, which depicted an eagle inside a wreath, served as proof to military police that its wearer was not going absent without leave.
