Winchester 100 .308

I just bought a Winchester 100 .308, 1961 made rifle. 13,000 range for serial number. I don't have a pic.
But I have a question, the stock is rough. How much would refinishing the stock hurt or help the value. For informational purposes, I'm very skilled at refinishing and restoration. I usually won't touch a stock with mild damage and wear. Because old guns should look old or "experienced " in my opinion. The for the help, in advance.
