Kuduae has mentioned in the past that the post WW2 actions have the primary extraction cams machined in the end of the barrel as opposed to the pre-war models where they are machined in the end of the action. This of course makes re-barreling tricky as the primary extraction cams are difficult to machine without special purpose built machinery. Externally on the bolt is easy but internally is a different story. I would like to see how the breech end of the barrel looks so that I can get an idea of how much and what sort of work is involved if one needs to re-barrel a post war model. If you can help that would be greatly appreciated.

Matt.
