Thank you Happy. I think I will try the mild household detergent first. As long as I don't get the stock too wet, it should be fine and I can still try other alternatives if that doesn't get it all off. I think I have some Minwax Antique oil, so I may try that. I'm reluctant to use the furniture stripper because I will probably have to really refinish the stock after that.
Ed, tried the mineral spirits wipe and did not see a noticeable change in appearance. It was neither darker nor lighter and the ink mark was still the same. I think that means that there is still a fair amount of finish in the cleaned part of the wood to prevent it from absorbing the mineral spirits (is that correct?). Also, does anyone have a suggestion on where I can get information on what type of finish was put on these older 853 stocks. That would really help when trying to find what will help get the ink out and would be valuable if I have to refinish the entire stock.I think I will try gently rubbing the ink with acetone next.
