Your top DI is for the West Coast AAF Training Center.

 

In the book "Distinctive Insignia of the U.S. Army Air Forces" by Jay Massaro the author lists two pieces. One is sterling and manufactured by LeVelle & Co. The other is a restrike and manufactured by the Sherman Manufacturing Co. Does yours have a hallmark?

 

The DI on the left is listed in the ASMIC Medical catalog as belonging to the 103rd Medical Battalion.
