Lots of caps on the forest floor for sure! My old KV was missing that cap, didn't bother the scope a bit either. Enjoy! You have a piece of history that will transport your Uncle's time to you every time you pick it up. Nothing better. I've my Grandfathers old Stevens pump he used to shoot car loads of ducks, pheasant, sharptail, and prairie chickens with. The day is always better when that old girl is in my hands, your's may well do the same for you.
