Huvius,

The bolt is absolutely original to the rifle, not a replacement !...
It's numbered, perfectly stamped and marked, and more than that it's of the first type with slim gas holes and machined for retaining the pointed cocking piece.
I have already encountered early made rifles with that kind of knob that is correct for the period.
The slightly faded slow rust blue finish match the other parts of the rifle and the headspace is perfect.
I will publish photos showing more details of that bolt, firing pin and cocking piece as soon I will get some time left.
