John, thanks a lot!!!
great links!
The reason of my question is because of the early 2 pieces bolt Nr. 3 and 21 on the picture . Blueprints of that model would be great.

How is that working with that system?
On the late M1 bolt it is just the weight of the metal keeping the bolt closed until the bullet is leafing the barrel, but on the early bolt there is that part Nr. 21 which makes me wondering!
