Karl, I would not think much of it. It's a shame walking trough life looking at the down side of things instead of the positive. With the Krag, there is plenty of the last. Congratulations with the acquisition, the stock looks fantastic.
This is one I inherited from my grandfather
The rear sight is removed, and a new one is welded on closer to the eye. Upper part is painted black. Probably to reduce reflection. And the extractor is worn out completely..
I'm thinking of fixing this up the rifle some day. It has killed about one hundred elg (similar to the moose) before it got 'retired' in the 90's, when it was no longer allowed for hunting.
