It must have been oiled again once or twice during the last 110 years. If you do a little maintenance wood can last literally a millennia in great condition, as we can see in some really old churches, castles and cathedrals here in Europe. Just make sure it does not dry up all the way, and don't bang it around. I also carefully oiled it once more to do my part. I want to pass the rifle on to someone who appreciates it someday, maybe it will become an Artifact (if it isn't already one) and last hundreds of years in great condition. That would be quite cool.
