Good morning all! I am the proud new owner of Sadie a 1938 Featherweight 221. She is in good working order but the black part I would like to see shine. What does one use for that? Also, how do you oil these? Yes, I know nothing about them. But the deal for $85 last night was too good to pass up. The ex-husband owed me money and I thought there is no way in &^% I was going to use this on bills. So I splurged on something I wanted. She looks so cute sitting on the sewing room table...like a little kid wanting to play...get thru work today then woohoo we have all weekend to party together and bond!
