Hi All, I'm trying to research a great uncle, George Marshall William Walker who is in the attached photo. I know he was an RAF Sgt at the time he was married (Jul 1942) as the photo shows but I have no idea about what he did. I presume from the half wing on his jacket he was aircrew but can anyone see what the letter might be? Can anyone suggest anywhere I can look other than applying for his record? Are there any websites that might help? Any help would be really appreciated. Thanks a lot, Michael
