Mislead by Poyer again (The M1903 Springfield Rifle and Its Variations)

In what he terms a Type 8 sear, he states "those manufactured by Smith Corona were often marked X."

In what he terms a Type 7 trigger, he states they were "marked.....X for Smith Corona." He further states that "The (sp) have the thin tip on the finger piece like the earlier triggers."

Pretty contradictory to the advice that I have received on this thread. I suppose he subscribed to the theory that X marks the spot for Smith Corona as an extension of their bolt marking practice.

Thanks again all for supplying me with good info.
