I've had a Finnish SA marked luger tool for years. The person who gave it to me said he didn't know if it was genuine or not. I'm thinking not original as it does not have the grooves machined into the back side where it lays up against the magazine. Because of this, it does not lay flat and the hole will not hook over the mag follower button. Does anyone here know anything about Finnish Luger tools? Any details or pics of known original tools would be much appreciated.
