I just received this project last week. Its very similar to an earlier post that claimed to be a Greifelt but there are no solid makers marks on this rifle. It does have a cursive "WK" on the bottom of the barrel, which I have been unable to identify, along with the designation 8.8X57. I slugged the barrel and it slugs at .3555 between lands and .348(I think that's what it was) between grooves. Short of chamber casting I've determined it to be a 9X57. The stock is obviously a modified military. The rifle originally came without a rear sight, I'm working on building a new one. It also had a spoon bolt that replaced the original bolt since the time that it was originally reworked, there was no work done to the bolt handle since it was welded on so I have also been working on reshaping and smoothing that out as you can see in the photos. Another issue is the set triggers, it will drop the kickoff but doesn't drop the sear all the way while set. There was some funky work done to this and I'm slowly but surely doing my best to fix these issues.

My hope is that somebody on here recognizes some of the original workmanship and tell me a little more about it. Its a neat rifle that has potential and I hope to bring it back to its former glory.
