I have the original bolt and bought one with a firing pin, which fit, but the firing pin has a crack where the safety knob slides in. The original firing pin, spring, knob and follower with plate were taken off some 55 years ago when the rifle was given to me by the guy that brought it back from the war and as I was only 11 years old. Could not have a real firing gun. Just now thinking that I might want to shoot it a few times. So bought some parts and they don't fit, plus the firing pin was cracked.
