Two Bars   Two medals on right likely Studleys with nice original and Issue Type 2 clasp on the Vittorio Veneto medal. Note the early unofficial army 'Aviation' clasp coupled with an original England clasp on a unique Slot Brooch.

Laurence - Sending you a PM re: the below badge.

Three Bars   Medal on right a Studley or some other non-contract but unique to 17th and 148th Aero.  

Four Bars

here's another view of Sergeant Hans Schultz and Krag.

Five Bars  

A badge like this cleaned by an ultrasonic cleaner will forever look like a badge cleaned by an ultrasonic cleaner.   The badge  originally had a gilt finish  and all that gilt finish corroded away.   And, not being marked “sterling”, I believe this badge is post WW2 (sterling was used to conserve strategic metals during the war).  I’d go for the full refund. And he should pay return shipping, as the item is not as advertised (far from it)   These badges are around.  Hold out for a nicer example.  

Six Campaign Bars

Thanks Scott. I live very close to Adair, and have spent time there in years past. I was trying to make an Adair connection, but can't come up with anything for the "L" either.

Thank you! I want to say the toggle switches are for either troubleshooting or setting up for the two system types. I'm not super familiar with jammers (due to the airframe I work on not having one), but that is my guess. Looks like the safety wire for system 1 is to keep it in "transmit" and system 2 has the other setting. The 130 photos are from old gunship types, this particular display case is filled with older Air Force items that I couldn't fit anywhere else.
