Peter raised concerns in post 2 about this bayonet. I have spent my whole working life in the metal working industry and know that it is very difficult to weld 2 pieces of metal together without leaving a trace/scar. One would normally expect to see some sign even when the metal has been ground/linished. The last picture in the set of photos in posts 1 appears to show a witness line or scar, as I have already stated, but we need to see better quality pictures to be sure that it has been welded.
