We're making progress on the 301A. Hubby got the feed dogs to move. After letting it soak up the sewing machine oil for a couple of days, I tried a few stitches and she sews beautifully. She's still a little clinky above the needle but is running much more quietly than she did during our first try. I'll have to live with the discoloration in the finish, I think, but the signs of rust are gone. She still needs a little more cosmetic cleaning. I love that she has a handle. Such a blessing!
