Bore looks nice and tight; she should be a shooter!
If you are looking for a new Nose-Cap, friend, Springfield Sporters in the US (website at ssporters.com, if I recall correctly) has some which have never been numbered. Last time I looked, they were asking about 11 Euros for one.
She is an Old Lady who has been to the dance and wore herself out. Then she visited this very nice doctor and now she is ready to do it all again. She IS History and you are now her guardian.
Yes, these things can be habit-forming. You should see my basement: the wreckage of 3 major Wars and a dozen Armies..... and most of it doesn't look any better than your old girl, but they all work (except for the real wrecks which ned a LOT of parts).
You have a Treasure,friend.
Welcome to the club!
