I was cleaning my gun today with an in the white barrel. I was thinking about military guns kept bright and shiny. Another thread was about polishing brass. Brick dust was a common issue for the men to use to buff. So, One had to have slipped and got in to the wood. Yet old besses I’ve seen don’t seem to have a lot of wear from that. The guns were varnished, but they must have freshened the wood finish pretty regular. Any idea on what the army boys oiled stocks with?
