Reading through some of the names on this photo, and I believe the signature in the bottom right corner (written upside down) to be Harry Langley (H.J Langley)
A relative of Harry Langley has kindly confirmed that he is in this photo, 2nd row from back, 5th from left. Would be great to identify a few more names/faces...
Following a visit to the National Archives, I have now been able to put names (and numbers) to most of the signatures to the best of my ability. Hoping to identify a few more... Spr J.
