Old Family members discharge Papers

[skeeter4206]

I was just looking through some of my stuff and was looking at these discharge papers and was curious about the David Martin discharge paper. In the upper left hand corner under his name has some letters and was wondering the meaning of them are. Do they represent the ships he was on or another meaning. I am assuming he served through WWII in the navy as a firefighter, but I know nothing about him or where he served. He is a family member that I never knew but was curious about his history. Maybe someone could help out.







Heres his dog tags and some metals that my grandfather had of his. There is one in the picture from WWI that I think is a family member Ben Walker. I also have is discharge papers and death certificate. Interesting that Ben was in the battle of the Somme and got gased and survived WWI, but died in 1924 from some kind of injury on a meat machine.
