Nigel, your last picture in post 1 showing a close up of the quillon seems to show a diagonal line exactly where I would expect there to be a weld scare if a "new" quillon had bee welded on to the cross guard. However, the lighting is not exactly great in this shot and it could just be a shadow in the picture. I believe that I am correct in saying that many of these quillon 1907s had their hooks removed around the beginning of WW1 but some have, apparently, given birth to new hooks in more recent years. Are you able to post some more close up pictures of the quillon better light, please?
