MPat, did you look close at the pictures I posted of the locking surfaces in the receiver and the top of the bolt's in the other thread? It's hard to tell from the way the bolt is positioned in your picture but the firing pin to me suggests the top of the locking lugs on the bolt may have been ground down. The firing pin looks home made but comparing it to an original the top front looks lower that it should be, if the top front of that pin set even with the top front of the bolt than the bolt also has been ground down which I mentioned in the the other thread as something I've seen done when the locking surfaces in the receiver are really distorted.
I will sell you the parts but I want to make sure you are not putting money into a gun that really can't safely be repaired. More pictures to compare to.
