In July of 2010 we recovered two .50 cal cases from a P-38 that was shot down near Mortree, France in 1944.
The marking on the bottom of the cases are K S 42 on one and R A 42 on the other.
Can anyone identify what these markings indicate?
(we have also several other small parts recovered from this crash site. The plane is from the 428th FS. The pilot was the father of a family member)
