Wouldn't that be neat! That would bear more and closer pics. The broad arrow is unmistakable. The bend mark is present and the other marks(PFD) are UK I think. It's not in the book I have. (Lee Enfield Story) I just checked Skennerton's book on the US Enfield. The bayonet is in fact the trials blade for the 276 cal pattern 1913. There were only a little over 1000 of these made. So, good catch Mick, it's rarer than rocking horse poo. Wonder what the value is???
