That's why all-original English guns command such premiums.
Nothing is uglier than one of those 100-year old English doubles with freshly blacked bbls/bits and a buffed action. Hideous things.
Personally, I dislike the look of reblacked bbls, refinished wood, recolored actions. I like wear and tear - as long as it is not mechanical. These guns are old. There's no shame in them looking that way.
After I hunt, I wipe down my guns and put them away. I've never had a problem with rusting or corrosion.
A couple of my doubles are as worn as this Fox and they're fine. I don't see the point in reblueing their bbls. I like them the way they are.
