In the above photo, the stretcher-bearer in the front row, far right, has been identified by John McKenzie as his grandfather, 6381 Pte Joseph Rhodes, MM, of Fairfield, who joined the 6 Field Ambulance on 8 March 1916. Gordon Williams transferred to the 12 Field Ambulance on 27 Oct 1916, so the photo would date to some time between March and October 1916.

Some while ago I managed to track down some relatives of Cec Dixon who provided the bottom photo, which looks very much like an older version of Cec.
Cecil Dixon on the left of this photo.
In the above photo, Cec Dixon is probably the man top left. He joined the 12 Field Ambulance on 20 Apr 1916, was wounded on 18 Oct 1917 and did not return to active service.
