Since you've finally found what it was you wanted to hear then why not tell us whether you should clean the stock off too or not?

Really??
No need to be negative.
I cant help others had a different opinion than yours.

By refinished, we mean someone sanded the stock and applied a new finish of some sort to it which are not factory original. The stock has been sanded as the markings are rather faint compared to if new. The stock condition also does not match the condition of the metal which is worn. The stock looks nearly new, very clean, few dings and no scrapes or scratches. They were removed by sanding. For a rifle to have that much wear on the metal but none on the stock, the stock was refinished. I can't answer to the metal, I've never heard of the Germans double stamping serial numbers but K98icon's are not my specialty. You mention the font, the font of the 7 appears to be stylized while the font of the other three numbers is very plain. Does not match in my opinion.

Thank you for your input.
