Red,
They phony up the blades these days because of their value. The makers mark is a real one, only that maker did not (we think) make SS daggers. They often start with a real blade and add a phony makers mark or a phony motto.
Also, crossguards were bought from suppliers and are not exclusive to any dagger maker.
The most complete reference book on SS daggers is by Tom Wittmann

Good luck
