a genealogist's sketchbook

OK, I’ve come to the bottom of my family militaria barrel but hope to identify things. This is a batch of things, of obviously mixed provenance, kept by my mother. A few messages to rec.heraldry helped narrow down the cardinals: likely something from WWII and hence from cousin Wilbur (army air forces) rather than from my grandfathers in WWI. But they could come from my grandfather Marvin, who subsequent to WWI was a reserve officer in Kentucky. But here’s the whole group of potentially military items:

The WWI Victory Medal and the ‘Honorably Discharged – World War’ pin must both have belonged to my mother’s father Carle Tucker, who had enlisted but was in an officer training camp when WWI ended and was presumably discharged as a private shortly thereafter. The small heraldic badge with motto ‘sustineo alas’ certainly belonged to my cousin Wilbur, who was in the Army Air Forces in WWII and trained in parachute repair / rigging at Chanute Field in Illinois; this was the DUI of the AAF Technical Services Command which was based at Chanute AFB. The cardinals remain a mystery; and what about the ’50-500′ star pin? And what about the thing that looks like a lieutenant’s bar but is light-blue enamel over gold-tone base metal? Something non-military? Something pre-WWI? I should warn that the baggie of goods out of which these came contained also a masonic pin and a pin from the Gloucester (Massachusetts) High School marching band. So: this bar could be non-military or have some other origin. Any ideas? I have Wilbur’s separation record but not one for either grandfather; perhaps I should request those records to see whether they help illuminate things.
