That K-22 is very nice doc540. I have a shipped in 1952 S&W K-22 Masterpiece. I only have the Gold Box and have no idea, if its original to the revolver, no grease pencil, etc, but it came with it. I wish I had the tools and paper work like you do. Its a 98% pistol though and I went over it with a microscope. I can't find where the finish has ever been tampered with. Its super accurate too. I even shot it at 50 yards one out of my friends Ransom Rest. It groups tight, I wish I could hold it that tight.
