Yearbook Update - 1939

We have a group photo taken in front of the Bessborough Armoury. The name of the organization is not listed, nor is the year. I believe it is 1939 due to the mix of uniforms. There is a separate list of last names corresponding to the photo but I have yet to match them with our current nominal roll. Are these new names to be added? First we need to find out the name of the uniform. I've found some info on Sgt Ashley Shatford who was a member of 1st Anti-Aircraft Regiment RCA. More to follow.
