I hope Mr Feren crosspinned or welded the cocking piece to the striker rod when he cut the knob off. Or did it start out that way? They did a few National Match 1903s with headless strikers.
The receiver is drilled and tapped for a peep sight. This might not be its first incarnation as a sporter. Or target rifle.
Look closely at the 6 o'clock position on the muzzle crown.
Looks like a somewhat worn star gauge stamp to me.
