WIN73, that guns has such grand patina, I just hope you realise that any over cleaning or refinish will SERIOUSLY devalue this gun and will will earn you a first class ticket to the devils hometown.
Don't worry. I have no plans to refinish it and since it was passed to me from my father about 30 years ago it hasn't been cleaned more than once or twice.
(Luke 11:21 KJV) When a strong man armed keepeth his palace, his goods are in peace:
(Luke 22:36 KJV) Then said he unto them, But now, he that hath a purse, let him take it, and likewise his scrip: and he that hath no sword, let him sell his garment, and buy one.
