I often think you should have to have a license to buy sandpaper, steel wool and scotch-bright pads, not firearms. So many fine examples have been ruined by the uninformed. Once I found my Holy Grail, a Winchester 92 in 32-20, first year of production, nice brown patina, with wood standing proud of the metal. When I arrived I found out that grandpa decided to spiff it up a bit with a vigorous sanding to the rifle with some 80 grit to do me a favour by cleaning it up. I damn near broke out in tears.
