Kilties in the Great War

I think the image needs to be bigger.
Can anyone tell me how delete ?

I've seen photos of Gordons in the Great War before and like this one the tartan doesn't seem to be the usual Gordon tartan. There doesn't seem to be evidence of the yellow line and also the sett doesn't seem to be normal either (Black Watch or Govenrment tartan). Can anyone throw any light on this ?
