Thanks Dave for posting Gordon's pictures. I sent the Camel photos to a
friend is a WW1 buff and have attached his replies to some of the photos. I
hope you find them interesting.

It's a non-pilot (no wings on his tunic) in front of a Camel. I can't make
out the man's cap badge; he could be a trainee pilot at a Training Depot
Station. If only the Camel's serial number was visible!
