Jack if I remember right the finish used by Browning in the 50s and 60s was lacquer.

Jim, I think any synthetic finish can and will eventually chip along the edges, and at the sides of deep scratches, and need to be retouched or refinished. I don't know why the manufacturers use lacquer, varnish, polyurethane, etc., except that it's quick and cheap to apply and looks pretty in a dealer's gun rack.
A good hand-rubbed oil finish is labor intensive, but if you like your gun it can be a labor of love. And the end result is as weatherproof as the painted-on stuff, but deeper into the wood, more protective, better looking and easier to maintain.
