Steve H, thanks...that was simple. I'm attaching a couple pics. I did get the safety installed correctly so now it will prevent the bolt from being turned. However, when cocked and on safe, still fires. It seems clear that the end of the locking bolt is broken/missing and the safety catch seems worn. Also, there is significant slop in the trigger. It pretty much flops freely with about a 1/2 inch of travel when not cocked. When cocked the travel is much less and less sloppy but I suspect still more than should be. Making progress. Seems most things are drop in fixes. The trigger may be more complicated I suspect.

Unrelated question. It appears, if I am interpreting properly it appears my magazine is a 2nd variation converted to 3rd since the barrel is marked HV for the high velocity rounds. Am I on target? Any particular rarity or uniqueness to this?

Thanks all.

Niels
