Mine is a pre M45 4 screw, shipped in 1958. It has PC diamond grips, numbered to the gun. Got it at a Cabelas, and after tax and shipping, around $2,000. No box or tools. It is a good 95%+. It also shoots to point of aim at 25 yards. Too much $$$? Yes, probably, as I paid $400 for a 98% K22 Outdoorsman. Big Larry
