Thanks Scanlan, my intent is to document mid 20th century long rifles and black powder gunsmiths, and then to honor them by shooting it. I took the lock back out to clean, and found it does have Harold Robbins signature.
Taterbug, I'm sure it would raise the point of impact. But I'm pleased with it hitting point of aim right now. I was using a 6 O'clock hold so it hit exactly where I was aiming. For plinking at a can or shooting at game, that's a lot easier than holding under to compensate for sights/loads set to hit higher.
