Raimey: If you look at the picture that shows the top view of the bolt action, you will see the screws. There are two screws just behind where the bolt slides back. It also has a square-looking opening between these screws. I figure there must have been another sight there? I can't make out some of the letters either. By the way, he's asking me $1,000; and I don't have any idea if the gun is worth that, would make a good trading gun later or be a worthwhile investment. I do appreciate all your help on this. George
